<p>Libxml2 is the XML C parser and toolkit developed for the Gnome project |
|
|
(but usable outside of the Gnome platform), it is free software available |
|
|
under the <a href="http://www.opensource.org/licenses/mit-license.html">MIT |
|
|
License</a>. XML itself is a metalanguage to design markup languages, i.e. |
|
|
text language where semantic and structure are added to the content using |
|
|
extra "markup" information enclosed between angle brackets. HTML is the most |
|
|
well-known markup language. Though the library is written in C <a |
|
|
href="python.html">a variety of language bindings</a> make it available in |
|
|
other environments.</p> |
|
|
|
|
|
<p>Libxml2 is known to be very portable, the library should build and work |
|
|
without serious troubles on a variety of systems (Linux, Unix, Windows, |
|
|
CygWin, MacOS, MacOS X, RISC Os, OS/2, VMS, QNX, MVS, VxWorks, ...)</p> |
|

<h2><a name="Introducti">Introduction</a></h2> |
|
|
|
|
|
<p>This document describes libxml, the <a |
|
|
href="http://www.w3.org/XML/">XML</a> C parser and toolkit developed for the |
|
|
<a href="http://www.gnome.org/">Gnome</a> project. <a |
|
|
href="http://www.w3.org/XML/">XML is a standard</a> for building tag-based |
|
|
structured documents/data.</p> |
|
|
|
|
|
<p>Here are some key points about libxml:</p> |
|
|
<ul> |
|
|
<li>Libxml2 exports Push (progressive) and Pull (blocking) type parser |
|
|
interfaces for both XML and HTML.</li> |
|
|
<li>Libxml2 can do DTD validation at parse time, using a parsed document |
|
|
instance, or with an arbitrary DTD.</li> |
|
|
<li>Libxml2 includes complete <a |
|
|
href="http://www.w3.org/TR/xpath">XPath</a>, <a |
|
|
href="http://www.w3.org/TR/xptr">XPointer</a> and <a |
|
|
href="http://www.w3.org/TR/xinclude">XInclude</a> implementations.</li> |
|
|
<li>It is written in plain C, making as few assumptions as possible, and |
|
|
sticking closely to ANSI C/POSIX for easy embedding. Works on |
|
|
Linux/Unix/Windows, ported to a number of other platforms.</li> |
|
|
<li>Basic support for HTTP and FTP client allowing applications to fetch |
|
|
remote resources.</li> |
|
|
<li>The design is modular, most of the extensions can be compiled out.</li> |
|
|
<li>The internal document representation is as close as possible to the <a |
|
|
href="http://www.w3.org/DOM/">DOM</a> interfaces.</li> |
|
|
<li>Libxml2 also has a <a |
|
|
href="http://www.megginson.com/SAX/index.html">SAX like interface</a>; |
|
|
the interface is designed to be compatible with <a |

<p>Yes. The MIT License allows you to keep proprietary the changes you |

|
<li><em>Where can I get libxml</em> ? |
|
|
<p>The original distribution comes from <a |
|

href="ftp://xmlsoft.org/libxml2/">xmlsoft.org</a> or <a |
|
|
href="ftp://ftp.gnome.org/pub/GNOME/sources/libxml2/2.6/">gnome.org</a></p> |
|
|
<p>Most Linux and BSD distributions include libxml, this is probably the |
|
|
safer way for end-users to use libxml.</p> |
|
|
<p>David Doolin provides precompiled Windows versions at <a |
|
|
href="http://www.ce.berkeley.edu/~doolin/code/libxmlwin32/ ">http://www.ce.berkeley.edu/~doolin/code/libxmlwin32/</a></p> |
|
|
</li> |
|
|
<p></p> |
|
|
<li><em>I see libxml and libxml2 releases, which one should I install ?</em> |
|
|
<ul> |
|
|
<li>If you are not constrained by backward compatibility issues with |
|
|
existing applications, install libxml2 only</li> |
|
|
<li>If you are not doing development, you can safely install both. |
|
|
Usually the packages <a |
|
|
href="http://rpmfind.net/linux/RPM/libxml.html">libxml</a> and <a |
|
|
href="http://rpmfind.net/linux/RPM/libxml2.html">libxml2</a> are |
|
|
compatible (this is not the case for development packages).</li> |
|
|
<li>If you are a developer and your system provides separate packaging |
|
|
for shared libraries and the development components, it is possible |
|
|
to install libxml and libxml2, and also <a |
|
|
href="http://rpmfind.net/linux/RPM/libxml-devel.html">libxml-devel</a> |
|
|
and <a |
|
|
href="http://rpmfind.net/linux/RPM/libxml2-devel.html">libxml2-devel</a> |
|
|
too for libxml2 >= 2.3.0</li> |
|
|
<li>If you are developing a new application, please develop against |
|
|
libxml2(-devel)</li> |
|
|
</ul> |
|
|
</li> |
|
|
<li><em>I can't install the libxml package, it conflicts with libxml0</em> |
|
|
<p>You probably have an old libxml0 package used to provide the shared |
|
|
library for libxml.so.0, you can probably safely remove it. The libxml |
|
|
packages provided on <a |
|
|
href="ftp://xmlsoft.org/libxml2/">xmlsoft.org</a> provide |
|
|
libxml.so.0</p> |
|
|
</li> |
|
|
<li><em>I can't install the libxml(2) RPM package due to failed |
|
|
dependencies</em> |
|
|
<p>The most generic solution is to re-fetch the latest src.rpm , and |
|
|
rebuild it locally with</p> |
|
|
<p><code>rpm --rebuild libxml(2)-xxx.src.rpm</code>.</p> |
|
|
<p>If everything goes well it will generate two binary rpm packages (one |
|
|
providing the shared libs and xmllint, and the other one, the -devel |
|
|
package, providing includes, static libraries and scripts needed to build |
|
|
applications with libxml(2)) that you can install locally.</p> |
|

|
|
|
|
<h3><a name="Compilatio">Compilation</a></h3> |
|
|
<ol> |
|
|
<li><em>What is the process to compile libxml2 ?</em> |
|
|
<p>As most UNIX libraries libxml2 follows the "standard":</p> |
|
|
<p><code>gunzip -c xxx.tar.gz | tar xvf -</code></p> |
|
|
<p><code>cd libxml-xxxx</code></p> |
|
|
<p><code>./configure --help</code></p> |
|
|
<p>to see the options, then the compilation/installation proper</p> |
|
|
<p><code>./configure [possible options]</code></p> |
|
|
<p><code>make</code></p> |
|
|
<p><code>make install</code></p> |
|
|
<p>At that point you may have to rerun ldconfig or a similar utility to |
|
|
update your list of installed shared libs.</p> |
|
|
</li> |
|
|
<li><em>What other libraries are needed to compile/install libxml2 ?</em> |
|
|
<p>Libxml2 does not require any other library, the normal C ANSI API |
|
|
should be sufficient (please report any violation to this rule you may |
|
|
find).</p> |
|
|
<p>However if found at configuration time libxml2 will detect and use the |
|
|
following libs:</p> |
|
|
<ul> |
|
|
<li><a href="http://www.info-zip.org/pub/infozip/zlib/">libz</a> : a |
|
|
highly portable and available widely compression library.</li> |
|
|
<li>iconv: a powerful character encoding conversion library. It is |
|
|
included by default in recent glibc libraries, so it doesn't need to |
|
|
be installed specifically on Linux. It now seems a <a |
|
|
href="http://www.opennc.org/onlinepubs/7908799/xsh/iconv.html">part |
|
|
of the official UNIX</a> specification. Here is one <a |
|
|
href="http://www.gnu.org/software/libiconv/">implementation of the |
|
|
library</a> which source can be found <a |
|
|
href="ftp://ftp.ilog.fr/pub/Users/haible/gnu/">here</a>.</li> |
|
|
</ul> |
|
|
</li> |
|
|
<p></p> |
|
|
<li><em>Make check fails on some platforms</em> |
|
|
<p>Sometimes the regression tests' results don't completely match the |
|
|
value produced by the parser, and the makefile uses diff to print the |
|
|
delta. On some platforms the diff return breaks the compilation process; |
|
|
if the diff is small this is probably not a serious problem.</p> |
|
|
<p>Sometimes (especially on Solaris) make checks fail due to limitations |
|
|
in make. Try using GNU-make instead.</p> |
|
|
</li> |
|
|
<li><em>I use the SVN version and there is no configure script</em> |
|
|
<p>The configure script (and other Makefiles) are generated. Use the |
|
|
autogen.sh script to regenerate the configure script and Makefiles, |
|
|
like:</p> |
|
|
<p><code>./autogen.sh --prefix=/usr --disable-shared</code></p> |
|
|
</li> |
|
|
<li><em>I have troubles when running make tests with gcc-3.0</em> |
|
|
<p>It seems the initial release of gcc-3.0 has a problem with the |
|
|
optimizer which miscompiles the URI module. Please use another |
|
|
compiler.</p> |
|
|
</li> |
|
|
</ol> |

<h3><a name="Developer">Developer</a> corner</h3> |
|
|
<ol> |
|
|
<li><em>Troubles compiling or linking programs using libxml2</em> |
|
|
<p>Usually the problem comes from the fact that the compiler doesn't get |
|
|
the right compilation or linking flags. There is a small shell script |
|
|
<code>xml2-config</code> which is installed as part of libxml2 usual |
|
|
install process which provides those flags. Use</p> |
|
|
<p><code>xml2-config --cflags</code></p> |
|
|
<p>to get the compilation flags and</p> |
|
|
<p><code>xml2-config --libs</code></p> |
|
|
<p>to get the linker flags. Usually this is done directly from the |
|
|
Makefile as:</p> |
|
|
<p><code>CFLAGS=`xml2-config --cflags`</code></p> |
|
|
<p><code>LIBS=`xml2-config --libs`</code></p> |
|
|
</li> |
|
|
<li><em>I want to install my own copy of libxml2 in my home directory and |
|
|
link my programs against it, but it doesn't work</em> |
|
|
<p>There are many different ways to accomplish this. Here is one way to |
|
|
do this under Linux. Suppose your home directory is <code>/home/user. |
|
|
</code>Then:</p> |
|
|
<ul> |
|
|
<li>Create a subdirectory, let's call it <code>myxml</code></li> |
|
|
<li>unpack the libxml2 distribution into that subdirectory</li> |
|
|
<li>chdir into the unpacked distribution |
|
|
(<code>/home/user/myxml/libxml2 </code>)</li> |
|
|
<li>configure the library using the "<code>--prefix</code>" switch, |
|
|
specifying an installation subdirectory in |
|
|
<code>/home/user/myxml</code>, e.g. |
|
|
<p><code>./configure --prefix /home/user/myxml/xmlinst</code> {other |
|
|
configuration options}</p> |
|
|
</li> |
|
|
<li>now run <code>make</code> followed by <code>make install</code></li> |
|
|
<li>At this point, the installation subdirectory contains the complete |
|
|
"private" include files, library files and binary program files (e.g. |
|
|
xmllint), located in |
|
|
<p><code>/home/user/myxml/xmlinst/lib, |
|
|
/home/user/myxml/xmlinst/include </code> and <code> |
|
|
/home/user/myxml/xmlinst/bin</code></p> |
|
|
respectively.</li> |
|
|
<li>In order to use this "private" library, you should first add it to |
|
|
the beginning of your default PATH (so that your own private program |
|
|
files such as xmllint will be used instead of the normal system |
|
|
ones). To do this, the Bash command would be |
|
|
<p><code>export PATH=/home/user/myxml/xmlinst/bin:$PATH</code></p> |
|
|
</li> |
|
|
<li>Now suppose you have a program <code>test1.c</code> that you would |
|
|
like to compile with your "private" library. Simply compile it using |
|
|
the command |
|
|
<p><code>gcc `xml2-config --cflags --libs` -o test test.c</code></p> |
|
|
Note that, because your PATH has been set with <code> |
|
|
/home/user/myxml/xmlinst/bin</code> at the beginning, the xml2-config |
|
|
program which you just installed will be used instead of the system |
|
|
default one, and this will <em>automatically</em> get the correct |
|
|
libraries linked with your program.</li> |
|
|

<p>Libxml2 will not <strong>invent</strong> spaces in the content of a |

|
<strong>NO</strong> way to guarantee that such a modification won't |

<p>In XML all characters in the content of the document are significant |

<p>The extra nodes you are wondering about are just that, text nodes with |

to forget. There is a function <a |

|
|
()</a> to remove those at parse time, but that's an heuristic, and its |

the libxml2 source</a> , I try to write code as clean and documented |

|
<li><em>How to validate a document a posteriori ?</em> |
|
|
<p>It is possible to validate documents which had not been validated at |
|
|
initial parsing time or documents which have been built from scratch |
|
|
using the API. Use the <a |
|
|
href="http://xmlsoft.org/html/libxml-valid.html#xmlValidateDtd">xmlValidateDtd()</a> |
|
|
function. It is also possible to simply add a DTD to an existing |
|
|
document:</p> |
|
|
<pre>xmlDocPtr doc; /* your existing document */ |
|
|
xmlDtdPtr dtd = xmlParseDTD(NULL, filename_of_dtd); /* parse the DTD */ |
|
|
|
|
|
dtd->name = xmlStrDup((xmlChar*)"root_name"); /* use the given root */ |
|
|
|
|
|
doc->intSubset = dtd; |
|
|
if (doc->children == NULL) xmlAddChild((xmlNodePtr)doc, (xmlNodePtr)dtd); |
|
|
else xmlAddPrevSibling(doc->children, (xmlNodePtr)dtd); |
|
|
</pre> |
|
|
</li> |
|
|
<li><em>So what is this funky "xmlChar" used all the time?</em> |
|
|
<p>It is a null terminated sequence of utf-8 characters. And only utf-8! |
|
|
You need to convert strings encoded in different ways to utf-8 before |
|
|
passing them to the API. This can be accomplished with the iconv library |
|
|
for instance.</p> |

<h2><a name="Reporting">Reporting bugs and getting help</a></h2> |
|
|
|
|
|
<p>Well, bugs or missing features are always possible, and I will make a |
|
|
point of fixing them in a timely fashion. The best way to report a bug is to |
|
|
use the <a href="http://bugzilla.gnome.org/buglist.cgi?product=libxml2">Gnome |
|
|
bug tracking database</a> (make sure to use the "libxml2" module name). I |
|
|
look at reports there regularly and it's good to have a reminder when a bug |
|
|
is still open. Be sure to specify that the bug is for the package libxml2.</p> |
|
|
|
|
|
<p>For small problems you can try to get help on IRC, the #xml channel on |
|
|
irc.gnome.org (port 6667) usually has a few people subscribed which may help |
|
|
(but there is no guarantee and if a real issue is raised it should go on the |
|
|
mailing-list for archival).</p> |
|
|
|
|
|
<p>There is also a mailing-list <a |
|
|
href="mailto:xml@gnome.org">xml@gnome.org</a> for libxml, with an <a |
|
|
href="http://mail.gnome.org/archives/xml/">on-line archive</a> (<a |
|
|
href="http://xmlsoft.org/messages">old</a>). To subscribe to this list, |
|
|
please visit the <a |
|
|
href="http://mail.gnome.org/mailman/listinfo/xml">associated Web</a> page and |
|
|
follow the instructions. <strong>Do not send code, I won't debug it</strong> |
|
|
(but patches are really appreciated!).</p> |
|
|
|
|
|
<p>Please note that with the current amount of virus and SPAM, sending mail |
|
|
to the list without being subscribed won't work. There is *far too many |
|
|
bounces* (in the order of a thousand a day !) I cannot approve them manually |
|
|
anymore. If your mail to the list bounced waiting for administrator approval, |
|
|
it is LOST ! Repost it and fix the problem triggering the error. Also please |
|
|
note that <span style="color: #FF0000; background-color: #FFFFFF">emails with |
|
|
a legal warning asking to not copy or redistribute freely the information |
|
|
they contain</span> are <strong>NOT</strong> acceptable for the mailing-list, |
|
|
such mail will as much as possible be discarded automatically, and are less |
|
|
likely to be answered if they made it to the list, <strong>DO NOT</strong> |
|
|
post to the list from an email address where such legal requirements are |
|
|
automatically added, get private paying support if you can't share |
|
|
information.</p> |
|
|
|
|
|
<p>Check the following <strong><span style="color: #FF0000">before |
|
|
posting</span></strong>:</p> |
|
|
<ul> |
|
|
<li>Read the <a href="FAQ.html">FAQ</a> and <a href="search.php">use the |
|
|
search engine</a> to get information related to your problem.</li> |
|
|
<li>Make sure you are <a href="ftp://xmlsoft.org/libxml2/">using a recent |
|
|
version</a>, and that the problem still shows up in a recent version.</li> |
|
|
<li>Check the <a href="http://mail.gnome.org/archives/xml/">list |
|
|
archives</a> to see if the problem was reported already. In this case |
|
|
there is probably a fix available, similarly check the <a |
|
|
href="http://bugzilla.gnome.org/buglist.cgi?product=libxml2">registered |
|
|
open bugs</a>.</li> |
|
|
<li>Make sure you can reproduce the bug with xmllint or one of the test |
|
|
programs found in source in the distribution.</li> |
|
|
<li>Please send the command showing the error as well as the input (as an |
|
|
attachment)</li> |
|
|
</ul> |
|
|
|
|
|
<p>Then send the bug with associated information to reproduce it to the <a |
|
|
href="mailto:xml@gnome.org">xml@gnome.org</a> list; if it's really libxml |
|
|
related I will approve it. Please do not send mail to me directly, it makes |
|
|
things really hard to track and in some cases I am not the best person to |
|
|
answer a given question, ask on the list.</p> |
|
|
|
|
|
<p>To <span style="color: #E50000">be really clear about support</span>:</p> |
|
|
<ul> |
|
|
<li>Support or help <span style="color: #E50000">requests MUST be sent to |
|
|
the list or on bugzilla</span> in case of problems, so that the Question |
|
|
and Answers can be shared publicly. Failing to do so carries the implicit |
|
|
message "I want free support but I don't want to share the benefits with |
|
|
others" and is not welcome. I will automatically Carbon-Copy the |
|
|
xml@gnome.org mailing list for any technical reply made about libxml2 or |
|
|
libxslt.</li> |
|
|
<li>There is <span style="color: #E50000">no guarantee of support</span>. If |
|
|
your question remains unanswered after a week, repost it, making sure you |
|
|
gave all the detail needed and the information requested.</li> |
|
|
<li>Failing to provide information as requested or double checking first |
|
|
for prior feedback also carries the implicit message "the time of the |
|
|
library maintainers is less valuable than my time" and might not be |
|
|
welcome.</li> |
|
|
</ul> |
|
|
|
|
|
<p>Of course, bugs reported with a suggested patch for fixing them will |
|
|
probably be processed faster than those without.</p> |
|
|
|
|
|
<p>If you're looking for help, a quick look at <a |
|
|
href="http://mail.gnome.org/archives/xml/">the list archive</a> may actually |
|
|
provide the answer. I usually send source samples when answering libxml2 |
|
|
usage questions. The <a |
|
|
href="http://xmlsoft.org/html/book1.html">auto-generated documentation</a> is |
|
|
not as polished as I would like (i need to learn more about DocBook), but |
|
|
it's a good starting point.</p> |

|
<h3>2.0.0: Apr 12 2000</h3> |
|
|
<ul> |
|
|
<li>First public release of libxml2. If you are using libxml, it's a good |
|
|
idea to check the 1.x to 2.x upgrade instructions. NOTE: while initially |
|
|
scheduled for Apr 3 the release occurred only on Apr 12 due to massive |
|
|
workload.</li> |
|
|
<li>The include are now located under $prefix/include/libxml (instead of |
|
|
$prefix/include/gnome-xml), they also are referenced by |
|
|
<pre>#include <libxml/xxx.h></pre> |
|
|
<p>instead of</p> |
|
|
<pre>#include "xxx.h"</pre> |
|
|
</li> |
|
|
<li>a new URI module for parsing URIs and following strictly RFC 2396</li> |
|
|
<li>the memory allocation routines used by libxml can now be overloaded |
|
|
dynamically by using xmlMemSetup()</li> |
|
|
<li>The previously CVS only tool tester has been renamed |
|
|
<strong>xmllint</strong> and is now installed as part of the libxml2 |
|
|
package</li> |
|
|
<li>The I/O interface has been revamped. There is now ways to plug in |
|
|
specific I/O modules, either at the URI scheme detection level using |
|
|
xmlRegisterInputCallbacks() or by passing I/O functions when creating a |
|
|
parser context using xmlCreateIOParserCtxt()</li> |
|
|
<li>there is a C preprocessor macro LIBXML_VERSION providing the version |
|
|
number of the libxml module in use</li> |
|
|
<li>a number of optional features of libxml can now be excluded at |
|
|
configure time (FTP/HTTP/HTML/XPath/Debug)</li> |
|
|
</ul> |
|
|
|
|
|
<h3>2.0.0beta: Mar 14 2000</h3> |
|
|
<ul> |
|
|
<li>This is a first Beta release of libxml version 2</li> |
|
|
<li>It's available only from<a href="ftp://xmlsoft.org/libxml2/">xmlsoft.org |
|
|
FTP</a>, it's packaged as libxml2-2.0.0beta and available as tar and |
|
|
RPMs</li> |
|
|
<li>This version is now the head in the Gnome CVS base, the old one is |
|
|
available under the tag LIB_XML_1_X</li> |
|
|
<li>This includes a very large set of changes. From a programmatic point |
|
|
of view applications should not have to be modified too much, check the |
|
|
<a href="upgrade.html">upgrade page</a></li> |
|
|
<li>Some interfaces may changes (especially a bit about encoding).</li> |
|
|
<li>the updates includes: |
|
|
<ul> |
|
|
<li>fix I18N support. ISO-Latin-x/UTF-8/UTF-16 (nearly) seems correctly |
|
|
handled now</li> |
|
|
<li>Better handling of entities, especially well-formedness checking |
|
|
and proper PEref extensions in external subsets</li> |
|
|
<li>DTD conditional sections</li> |
|
|
<li>Validation now correctly handle entities content</li> |
|
|
<li><a href="http://rpmfind.net/tools/gdome/messages/0039.html">change |
|
|
structures to accommodate DOM</a></li> |
|
|
</ul> |
|
|
</li> |
|
|
<li>Serious progress were made toward compliance, <a |
|
|
href="conf/result.html">here are the result of the test</a> against the |
|
|
OASIS testsuite (except the Japanese tests since I don't support that |
|
|
encoding yet). This URL is rebuilt every couple of hours using the CVS |
|
|
head version.</li> |
|
|
</ul> |
|
|
|
|
|
<h3>1.8.7: Mar 6 2000</h3> |
|
|
<ul> |
|
|
<li>This is a bug fix release:</li> |
|
|
<li>It is possible to disable the ignorable blanks heuristic used by |
|
|
libxml-1.x, a new function xmlKeepBlanksDefault(0) will allow this. Note |
|
|
that for adherence to XML spec, this behaviour will be disabled by |
|
|
default in 2.x . The same function will allow to keep compatibility for |
|
|
old code.</li> |
|
|
<li>Blanks in <a> </a> constructs are not ignored anymore, |
|
|
avoiding heuristic is really the Right Way :-\</li> |
|
|
<li>The unchecked use of snprintf which was breaking libxml-1.8.6 |
|
|
compilation on some platforms has been fixed</li> |

|
|
<ul> |
|
|

|
|
<ul> |
|
|
<li>The basic type for strings manipulated by libxml has been renamed in |
|
|
1.7.1 from <strong>CHAR</strong> to <strong>xmlChar</strong>. The reason |

on non WIN32 environment, compatibility is provided by the way of a |
|
|
<strong>#define </strong>.</li> |
|
|
<li>Changed another error : the use of a structure field called errno, and |

<li>Serious memory leaks fixed (there is now a <a |
|
|
href="html/libxml-xmlmemory.html">memory wrapper</a> module)</li> |
|
|
<li>Improvement of <a href="http://www.w3.org/TR/xpath">XPath</a> |
|
|
implementation</li> |
|
|
<li>Added an HTML parser front-end</li> |
|
|
</ul> |

<h2><a name="XML">XML</a></h2> |
|
|
|
|
|
<p><a href="http://www.w3.org/TR/REC-xml">XML is a standard</a> for |
|
|
markup-based structured documents. Here is <a name="example">an example XML |
|
|
document</a>:</p> |
|
|
<pre><?xml version="1.0"?> |
|
|
<EXAMPLE prop1="gnome is great" prop2="&amp; linux too"> |
|

<head> |

<title>Welcome to Gnome</title> |

<title>The Linux adventure</title> |

<p>bla bla bla ...</p> |
|

<image href="linus.gif"/> |
|
|
<p>...</p> |
|
|
</chapter> |
|
|
</EXAMPLE></pre> |
|
|
|
|
|
<p>The first line specifies that it is an XML document and gives useful |
|
|
information about its encoding. Then the rest of the document is a text |
|
|
format whose structure is specified by tags between brackets. <strong>Each |
|
|
tag opened has to be closed</strong>. XML is pedantic about this. However, if |
|
|
a tag is empty (no content), a single tag can serve as both the opening and |
|
|
closing tag if it ends with <code>/></code> rather than with |
|
|
<code>></code>. Note that, for example, the image tag has no content (just |
|
|
an attribute) and is closed by ending the tag with <code>/></code>.</p> |
|
|
|
|
|
<p>XML can be applied successfully to a wide range of tasks, ranging from |
|
|
long term structured document maintenance (where it follows the steps of |
|
|
SGML) to simple data encoding mechanisms like configuration file formatting |
|
|
(glade), spreadsheets (gnumeric), or even shorter lived documents such as |
|
|
WebDAV where it is used to encode remote calls between a client and a |
|
|
server.</p> |

of the Python bindings</a>.</p> |
|
|
|
|
|
<p>Note to people interested in building bindings, the API is formalized as |
|
|
<a href="libxml2-api.xml">an XML API description file</a> which allows to |
|
|
automate a large part of the Python bindings, this includes function |
|
|
descriptions, enums, structures, typedefs, etc... The Python script used to |
|
|
build the bindings is python/generator.py in the source distribution.</p> |
|
|
|
|
|
<p>To install the Python bindings there are 2 options:</p> |
|
|
<ul> |
|
|
<li>If you use an RPM based distribution, simply install the <a |
|
|
href="http://rpmfind.net/linux/rpm2html/search.php?query=libxml2-python">libxml2-python |
|
|
RPM</a> (and if needed the <a |
|
|
href="http://rpmfind.net/linux/rpm2html/search.php?query=libxslt-python">libxslt-python |
|
|
RPM</a>).</li> |
|
|
<li>Otherwise use the <a href="ftp://xmlsoft.org/libxml2/python/">libxml2-python |
|
|
module distribution</a> corresponding to your installed version of |
|
|
libxml2 and libxslt. Note that to install it you will need both libxml2 |
|
|
and libxslt installed and run "python setup.py build install" in the |
|
|
module tree.</li> |
|
|
</ul> |
|
|
|
|
|
<p>The distribution includes a set of examples and regression tests for the |
|
|
python bindings in the <code>python/tests</code> directory. Here are some |
|
|
excerpts from those tests:</p> |
|
|
|
|
|
<h3>tst.py:</h3> |
|
|
|
|
|
<p>This is a basic test of the file interface and DOM navigation:</p> |
|
|
<pre>import libxml2, sys |
|
|
|
|
|
doc = libxml2.parseFile("tst.xml") |
|
|
if doc.name != "tst.xml": |
|
|
print "doc.name failed" |
|
|
sys.exit(1) |
|
|
root = doc.children |
|
|
if root.name != "doc": |
|
|
print "root.name failed" |
|
|
sys.exit(1) |
|
|
child = root.children |
|
|
if child.name != "foo": |
|
|
print "child.name failed" |
|
|
sys.exit(1) |
|
|
doc.freeDoc()</pre> |
|
|
|
|
|
<p>The Python module is called libxml2; parseFile is the equivalent of |
|
|
xmlParseFile (most of the bindings are automatically generated, and the xml |
|
|
prefix is removed and the casing convention are kept). All node seen at the |
|
|
binding level share the same subset of accessors:</p> |
|
|
<ul> |
|
|
<li><code>name</code> : returns the node name</li> |
|
|
<li><code>type</code> : returns a string indicating the node type</li> |
|
|
<li><code>content</code> : returns the content of the node, it is based on |
|
|
xmlNodeGetContent() and hence is recursive.</li> |
|
|
<li><code>parent</code> , <code>children</code>, <code>last</code>, |
|
|
<code>next</code>, <code>prev</code>, <code>doc</code>, |
|
|
<code>properties</code>: pointing to the associated element in the tree, |
|
|
those may return None in case no such link exists.</li> |
|
|
</ul> |
|
|
|
|
|
<p>Also note the need to explicitly deallocate documents with freeDoc() . |
|
|
Reference counting for libxml2 trees would need quite a lot of work to |
|
|
function properly, and rather than risk memory leaks if not implemented |
|
|
correctly it sounds safer to have an explicit function to free a tree. The |
|
|
wrapper python objects like doc, root or child are them automatically garbage |
|
|
collected.</p> |
|
|
|
|
|
<h3>validate.py:</h3> |
|
|
|
|
|
<p>This test check the validation interfaces and redirection of error |
|
|
messages:</p> |
|
|
<pre>import libxml2 |
|
|
|
|
|
#deactivate error messages from the validation |
|
|
def noerr(ctx, str): |
|
|
pass |
|
|
|
|
|
libxml2.registerErrorHandler(noerr, None) |
|
|
|
|
|
ctxt = libxml2.createFileParserCtxt("invalid.xml") |
|
|
ctxt.validate(1) |
|
|
ctxt.parseDocument() |
|
|
doc = ctxt.doc() |
|
|
valid = ctxt.isValid() |
|
|
doc.freeDoc() |
|
|
if valid != 0: |
|
|
print "validity check failed"</pre> |
|
|
|
|
|
<p>The first thing to notice is the call to registerErrorHandler(), it |
|
|
defines a new error handler global to the library. It is used to avoid seeing |
|
|
the error messages when trying to validate the invalid document.</p> |
|
|
|
|
|
<p>The main interest of that test is the creation of a parser context with |
|
|
createFileParserCtxt() and how the behaviour can be changed before calling |
|
|
parseDocument() . Similarly the information resulting from the parsing phase |
|
|
is also available using context methods.</p> |
|
|
|
|
|
<p>Contexts like nodes are defined as class and the libxml2 wrappers maps the |
|
|
C function interfaces in terms of objects method as much as possible. The |
|
|
best to get a complete view of what methods are supported is to look at the |
|
|
libxml2.py module containing all the wrappers.</p> |
|
|
|
|
|
<h3>push.py:</h3> |
|
|
|
|
|
<p>This test show how to activate the push parser interface:</p> |
|
|
<pre>import libxml2 |
|
|
|
|
|
ctxt = libxml2.createPushParser(None, "<foo", 4, "test.xml") |
|
|
ctxt.parseChunk("/>", 2, 1) |
|
|
doc = ctxt.doc() |
|
|
|
|
|
doc.freeDoc()</pre> |
|
|
|
|
|
<p>The context is created with a special call based on the |
|
|
xmlCreatePushParser() from the C library. The first argument is an optional |
|
|
SAX callback object, then the initial set of data, the length and the name of |
|
|
the resource in case URI-References need to be computed by the parser.</p> |
|
|
|
|
|
<p>Then the data are pushed using the parseChunk() method, the last call |
|
|
setting the third argument terminate to 1.</p> |
|
|
|
|
|
<h3>pushSAX.py:</h3> |
|
|
|
|
|
<p>this test show the use of the event based parsing interfaces. In this case |
|
|
the parser does not build a document, but provides callback information as |
|
|
the parser makes progresses analyzing the data being provided:</p> |
|
|
<pre>import libxml2 |
|
|
log = "" |
|
|
|
|
|
class callback: |
|
|
def startDocument(self): |
|
|
global log |
|
|
log = log + "startDocument:" |
|
|
|
|
|
def endDocument(self): |
|
|
global log |
|
|
log = log + "endDocument:" |
|
|
|
|
|
def startElement(self, tag, attrs): |
|
|
global log |
|
|
log = log + "startElement %s %s:" % (tag, attrs) |
|
|
|
|
|
def endElement(self, tag): |
|
|
global log |
|
|
log = log + "endElement %s:" % (tag) |
|
|
|
|
|
def characters(self, data): |
|
|
global log |
|
|
log = log + "characters: %s:" % (data) |
|
|
|
|
|
def warning(self, msg): |
|
|
global log |
|
|
log = log + "warning: %s:" % (msg) |
|
|
|
|
|
def error(self, msg): |
|
|
global log |
|
|
log = log + "error: %s:" % (msg) |
|
|
|
|
|
def fatalError(self, msg): |
|
|
global log |
|
|
log = log + "fatalError: %s:" % (msg) |
|
|
|
|
|
handler = callback() |
|
|
|
|
|
ctxt = libxml2.createPushParser(handler, "<foo", 4, "test.xml") |
|
|
chunk = " url='tst'>b" |
|
|
ctxt.parseChunk(chunk, len(chunk), 0) |
|
|
chunk = "ar</foo>" |
|
|
ctxt.parseChunk(chunk, len(chunk), 1) |
|
|
|
|
|
reference = "startDocument:startElement foo {'url': 'tst'}:" + \ |
|
|
"characters: bar:endElement foo:endDocument:" |
|
|
if log != reference: |
|
|
print "Error got: %s" % log |
|
|
print "Expected: %s" % reference</pre> |
|
|
|
|
|
<p>The key object in that test is the handler, it provides a number of entry |
|
|
points which can be called by the parser as it makes progresses to indicate |
|
|
the information set obtained. The full set of callback is larger than what |
|
|
the callback class in that specific example implements (see the SAX |
|
|
definition for a complete list). The wrapper will only call those supplied by |
|
|
the object when activated. The startElement receives the names of the element |
|
|
and a dictionary containing the attributes carried by this element.</p> |
|
|
|
|
|
<p>Also note that the reference string generated from the callback shows a |
|
|
single character call even though the string "bar" is passed to the parser |
|
|
from 2 different call to parseChunk()</p> |
|
|
|
|
|
<h3>xpath.py:</h3> |
|
|
|
|
|
<p>This is a basic test of XPath wrappers support</p> |
|
|
<pre>import libxml2 |
|
|
|
|
|
doc = libxml2.parseFile("tst.xml") |
|
|
ctxt = doc.xpathNewContext() |
|
|
res = ctxt.xpathEval("//*") |
|
|
if len(res) != 2: |
|
|
print "xpath query: wrong node set size" |
|
|
sys.exit(1) |
|
|
if res[0].name != "doc" or res[1].name != "foo": |
|
|
print "xpath query: wrong node set value" |
|
|
sys.exit(1) |
|
|
doc.freeDoc() |
|
|
ctxt.xpathFreeContext()</pre> |
|
|
|
|
|
<p>This test parses a file, then create an XPath context to evaluate XPath |
|
|
expression on it. The xpathEval() method execute an XPath query and returns |
|
|
the result mapped in a Python way. String and numbers are natively converted, |
|
|
and node sets are returned as a tuple of libxml2 Python nodes wrappers. Like |
|
|
the document, the XPath context need to be freed explicitly, also not that |
|
|
the result of the XPath query may point back to the document tree and hence |
|
|
the document must be freed after the result of the query is used.</p> |
|
|
|
|
|
<h3>xpathext.py:</h3> |
|
|
|
|
|
<p>This test shows how to extend the XPath engine with functions written in |
|
|
python:</p> |
|
|
<pre>import libxml2 |
|
|
|
|
|
def foo(ctx, x): |
|
|
return x + 1 |
|
|
|
|
|
doc = libxml2.parseFile("tst.xml") |
|
|
ctxt = doc.xpathNewContext() |
|
|
libxml2.registerXPathFunction(ctxt._o, "foo", None, foo) |
|
|
res = ctxt.xpathEval("foo(1)") |
|
|
if res != 2: |
|
|
print "xpath extension failure" |
|
|
doc.freeDoc() |
|
|
ctxt.xpathFreeContext()</pre> |
|
|
|
|
|
<p>Note how the extension function is registered with the context (but that |
|
|
part is not yet finalized, this may change slightly in the future).</p> |
|
|
|
|
|
<h3>tstxpath.py:</h3> |
|
|
|
|
|
<p>This test is similar to the previous one but shows how the extension |
|
|
function can access the XPath evaluation context:</p> |
|
|
<pre>def foo(ctx, x): |
|
|
global called |
|
|
|
|
|
# |
|
|
# test that access to the XPath evaluation contexts |
|
|
# |
|
|
pctxt = libxml2.xpathParserContext(_obj=ctx) |
|
|
ctxt = pctxt.context() |
|
|
called = ctxt.function() |
|
|
return x + 1</pre> |
|
|
|
|
|
<p>All the interfaces around the XPath parser(or rather evaluation) context |
|
|
are not finalized, but it should be sufficient to do contextual work at the |
|
|
evaluation point.</p> |
|
|
|
|
|
<h3>Memory debugging:</h3> |
|
|
|
|
|
<p>last but not least, all tests starts with the following prologue:</p> |
|
|
<pre>#memory debug specific |
|
|
libxml2.debugMemory(1)</pre> |
|
|
|
|
|
<p>and ends with the following epilogue:</p> |
|
|
<pre>#memory debug specific |
|
|
libxml2.cleanupParser() |
|
|
if libxml2.debugMemory(1) == 0: |
|
|
print "OK" |
|
|
else: |
|
|
print "Memory leak %d bytes" % (libxml2.debugMemory(1)) |
|
|
libxml2.dumpMemory()</pre> |
|
|
|
|
|
<p>Those activate the memory debugging interface of libxml2 where all |
|
|
allocated block in the library are tracked. The prologue then cleans up the |
|
|
library state and checks that all allocated memory has been freed. If not it |
|
|
calls dumpMemory() which saves that list in a <code>.memdump</code> file.</p> |
|
|
|
|
|
<h2><a name="architecture">libxml2 architecture</a></h2> |
|
|
|
|
|
<p>Libxml2 is made of multiple components; some of them are optional, and |
|
|
most of the block interfaces are public. The main components are:</p> |
|
|
<ul> |
|
|
<li>an Input/Output layer</li> |
|
|
<li>FTP and HTTP client layers (optional)</li> |
|
|
<li>an Internationalization layer managing the encodings support</li> |
|
|
<li>a URI module</li> |
|
|
<li>the XML parser and its basic SAX interface</li> |
|
|
<li>an HTML parser using the same SAX interface (optional)</li> |
|
|
<li>a SAX tree module to build an in-memory DOM representation</li> |
|
|
<li>a tree module to manipulate the DOM representation</li> |
|
|
<li>a validation module using the DOM representation (optional)</li> |
|
|
<li>an XPath module for global lookup in a DOM representation |
|
|
(optional)</li> |
|
|
<li>a debug module (optional)</li> |
|
|
</ul> |
|
|
|
|
|
<p>Graphically this gives the following:</p> |
|
|
|
|
|
<p><img src="libxml.gif" alt="a graphical view of the various"></p> |
|
|
|
|
|
<p></p> |
|
|
|
|
|
<h2><a name="tree">The tree output</a></h2> |
|
|
|
|
|
<p>The parser returns a tree built during the document analysis. The value |
|
|
returned is an <strong>xmlDocPtr</strong> (i.e., a pointer to an |
|
|
<strong>xmlDoc</strong> structure). This structure contains information such |
|
|
as the file name, the document type, and a <strong>children</strong> pointer |
|
|
which is the root of the document (or more exactly the first child under the |
|
|
root which is the document). The tree is made of <strong>xmlNode</strong>s, |
|
|
chained in double-linked lists of siblings and with a children<->parent |
|
|
relationship. An xmlNode can also carry properties (a chain of xmlAttr |
|
|
structures). An attribute may have a value which is a list of TEXT or |
|
|
ENTITY_REF nodes.</p> |
|
|
|
|
|
<p>Here is an example (erroneous with respect to the XML spec since there |
|
|
should be only one ELEMENT under the root):</p> |
|
|
|
|
|
<p><img src="structure.gif" alt=" structure.gif "></p> |
|
|
|
|
|
<p>In the source package there is a small program (not installed by default) |
|
|
called <strong>xmllint</strong> which parses XML files given as argument and |
|
|
prints them back as parsed. This is useful for detecting errors both in XML |
|
|
code and in the XML parser itself. It has an option <strong>--debug</strong> |
|
|
which prints the actual in-memory structure of the document; here is the |
|
|
result with the <a href="#example">example</a> given before:</p> |
|
|
<pre>DOCUMENT |
|
|

<p>This should be useful for learning the internal representation model.</p> |
|
|
|
|
|
<h2><a name="interface">The SAX interface</a></h2> |
|
|
|
|
|
<p>Sometimes the DOM tree output is just too large to fit reasonably into |
|
|
memory. In that case (and if you don't expect to save back the XML document |
|
|
loaded using libxml), it's better to use the SAX interface of libxml. SAX is |
|
|
a <strong>callback-based interface</strong> to the parser. Before parsing, |
|
|
the application layer registers a customized set of callbacks which are |
|
|
called by the library as it progresses through the XML input.</p> |
|
|
|
|
|
<p>To get more detailed step-by-step guidance on using the SAX interface of |
|
|
libxml, see the <a |
|
|
href="http://www.jamesh.id.au/articles/libxml-sax/libxml-sax.html">nice |
|
|
documentation</a>.written by <a href="mailto:james@daa.com.au">James |
|
|
Henstridge</a>.</p> |
|
|
|
|
|
<p>You can debug the SAX behaviour by using the <strong>testSAX</strong> |
|
|
program located in the gnome-xml module (it's usually not shipped in the |
|
|
binary packages of libxml, but you can find it in the tar source |
|
|
distribution). Here is the sequence of callbacks that would be reported by |
|
|
testSAX when parsing the example XML document shown earlier:</p> |
|
|
<pre>SAX.setDocumentLocator() |
|
|
SAX.startDocument() |

|
<p>Most of the other interfaces of libxml2 are based on the DOM tree-building |
|
|
facility, so nearly everything up to the end of this document presupposes the |
|
|
use of the standard DOM tree build. Note that the DOM tree itself is built by |
|
|
a set of registered default callbacks, without internal specific |
|
|
interface.</p> |

<h3><a name="General5">General overview</a></h3> |
|
|
|
|
|
<p>Well what is validation and what is a DTD ?</p> |
|
|
|
|
|
<p>DTD is the acronym for Document Type Definition. This is a description of |
|
|
the content for a family of XML files. This is part of the XML 1.0 |
|
|
specification, and allows one to describe and verify that a given document |
|
|
instance conforms to the set of rules detailing its structure and content.</p> |
|
|
|
|
|
<p>Validation is the process of checking a document against a DTD (more |
|
|
generally against a set of construction rules).</p> |
|
|
|
|
|
<p>The validation process and building DTDs are the two most difficult parts |
|
|
of the XML life cycle. Briefly a DTD defines all the possible elements to be |
|
|
found within your document, what is the formal shape of your document tree |
|
|
(by defining the allowed content of an element; either text, a regular |
|
|
expression for the allowed list of children, or mixed content i.e. both text |
|
|
and children). The DTD also defines the valid attributes for all elements and |
|
|
the types of those attributes.</p> |
|
|
|

<h3><a name="Simple1">Simple rules</a></h3> |
|
|
|
|
|
<p>Writing DTDs can be done in many ways. The rules to build them if you need |
|
|
something permanent or something which can evolve over time can be radically |
|
|
different. Really complex DTDs like DocBook ones are flexible but quite |
|
|
harder to design. I will just focus on DTDs for a formats with a fixed simple |
|
|
structure. It is just a set of basic rules, and definitely not exhaustive nor |
|
|
usable for complex DTD design.</p> |
|
|
|
|
|
<h4><a name="reference1">How to reference a DTD from a document</a>:</h4> |
|
|
|
|
|
<p>Assuming the top element of the document is <code>spec</code> and the dtd |
|
|
is placed in the file <code>mydtd</code> in the subdirectory |
|
|
<code>dtds</code> of the directory from where the document were loaded:</p> |
|
|
|
|
|
<p><code><!DOCTYPE spec SYSTEM "dtds/mydtd"></code></p> |
|
|
|
|
|
<p>Notes:</p> |
|
|
<ul> |
|
|
<li>The system string is actually an URI-Reference (as defined in <a |
|
|
href="http://www.ietf.org/rfc/rfc2396.txt">RFC 2396</a>) so you can use a |
|
|
full URL string indicating the location of your DTD on the Web. This is a |
|
|
really good thing to do if you want others to validate your document.</li> |
|
|
<li>It is also possible to associate a <code>PUBLIC</code> identifier (a |
|
|
magic string) so that the DTD is looked up in catalogs on the client side |
|
|
without having to locate it on the web.</li> |
|
|
<li>A DTD contains a set of element and attribute declarations, but they |
|
|
don't define what the root of the document should be. This is explicitly |
|
|
told to the parser/validator as the first element of the |
|
|
<code>DOCTYPE</code> declaration.</li> |
|
|
</ul> |
|
|
|
|
|
<h4><a name="Declaring2">Declaring elements</a>:</h4> |
|
|
|
|
|
<p>The following declares an element <code>spec</code>:</p> |
|
|
|
|
|
<p><code><!ELEMENT spec (front, body, back?)></code></p> |
|
|
|
|
|
<p>It also expresses that the spec element contains one <code>front</code>, |
|
|
one <code>body</code> and one optional <code>back</code> children elements in |
|
|
this order. The declaration of one element of the structure and its content |
|
|
are done in a single declaration. Similarly the following declares |
|
|
<code>div1</code> elements:</p> |
|
|
|
|
|
<p><code><!ELEMENT div1 (head, (p | list | note)*, div2?)></code></p> |
|
|
|
|
|
<p>which means div1 contains one <code>head</code> then a series of optional |
|
|
<code>p</code>, <code>list</code>s and <code>note</code>s and then an |
|
|
optional <code>div2</code>. And last but not least an element can contain |
|
|
text:</p> |
|
|
|
|
|
<p><code><!ELEMENT b (#PCDATA)></code></p> |
|
|
|
|
|
<p><code>b</code> contains text or being of mixed content (text and elements |
|
|
in no particular order):</p> |
|
|
|
|
|
<p><code><!ELEMENT p (#PCDATA|a|ul|b|i|em)*></code></p> |
|
|
|
|
|
<p><code>p </code>can contain text or <code>a</code>, <code>ul</code>, |
|
|
<code>b</code>, <code>i </code>or <code>em</code> elements in no particular |
|
|
order.</p> |
|
|
|
|
|
<h4><a name="Declaring1">Declaring attributes</a>:</h4> |
|
|
|
|
|
<p>Again the attributes declaration includes their content definition:</p> |
|
|
|
|
|
<p><code><!ATTLIST termdef name CDATA #IMPLIED></code></p> |
|
|
|
|
|
<p>means that the element <code>termdef</code> can have a <code>name</code> |
|
|
attribute containing text (<code>CDATA</code>) and which is optional |
|
|
(<code>#IMPLIED</code>). The attribute value can also be defined within a |
|
|
set:</p> |
|
|
|
|
|
<p><code><!ATTLIST list type (bullets|ordered|glossary) |
|
|
"ordered"></code></p> |
|
|
|
|
|
<p>means <code>list</code> element have a <code>type</code> attribute with 3 |
|
|
allowed values "bullets", "ordered" or "glossary" and which default to |
|
|
"ordered" if the attribute is not explicitly specified.</p> |
|
|
|
|
|
<p>The content type of an attribute can be text (<code>CDATA</code>), |
|
|
anchor/reference/references |
|
|
(<code>ID</code>/<code>IDREF</code>/<code>IDREFS</code>), entity(ies) |
|
|
(<code>ENTITY</code>/<code>ENTITIES</code>) or name(s) |
|
|
(<code>NMTOKEN</code>/<code>NMTOKENS</code>). The following defines that a |
|
|
<code>chapter</code> element can have an optional <code>id</code> attribute |
|
|
of type <code>ID</code>, usable for reference from attribute of type |
|
|
IDREF:</p> |
|
|
|
|
|
<p><code><!ATTLIST chapter id ID #IMPLIED></code></p> |
|
|
|
|
|
<p>The last value of an attribute definition can be <code>#REQUIRED |
|
|
</code>meaning that the attribute has to be given, <code>#IMPLIED</code> |
|
|
meaning that it is optional, or the default value (possibly prefixed by |
|
|
<code>#FIXED</code> if it is the only allowed).</p> |
|
|
|
|
|
<p>Notes:</p> |
|
|
<ul> |
|
|
<li>Usually the attributes pertaining to a given element are declared in a |
|
|
single expression, but it is just a convention adopted by a lot of DTD |
|
|
writers: |
|
|
<pre><!ATTLIST termdef |
|
|
id ID #REQUIRED |
|
|
name CDATA #IMPLIED></pre> |
|
|
<p>The previous construct defines both <code>id</code> and |
|
|
<code>name</code> attributes for the element <code>termdef</code>.</p> |
|
|
</li> |
|
|
</ul> |

<h3><a name="Some1">Some examples</a></h3> |
|
|
|
|
|
<p>The directory <code>test/valid/dtds/</code> in the libxml2 distribution |
|
|
contains some complex DTD examples. The example in the file |
|
|
<code>test/valid/dia.xml</code> shows an XML file where the simple DTD is |
|
|
directly included within the document.</p> |
|
|
|
|
|
<h3><a name="validate1">How to validate</a></h3> |
|
|
|
|
|
<p>The simplest way is to use the xmllint program included with libxml. The |
|
|
<code>--valid</code> option turns-on validation of the files given as input. |
|
|
For example the following validates a copy of the first revision of the XML |
|
|
1.0 specification:</p> |
|
|
|
|
|
<p><code>xmllint --valid --noout test/valid/REC-xml-19980210.xml</code></p> |
|
|
|
|
|
<p>the -- noout is used to disable output of the resulting tree.</p> |
|
|
|
|
|
<p>The <code>--dtdvalid dtd</code> allows validation of the document(s) |
|
|
against a given DTD.</p> |
|
|
|
|
|
<p>Libxml2 exports an API to handle DTDs and validation, check the <a |
|
|
href="http://xmlsoft.org/html/libxml-valid.html">associated |
|
|
description</a>.</p> |
|
|
|
|
|
<h3><a name="Other1">Other resources</a></h3> |
|
|
|
|
|
<p>DTDs are as old as SGML. So there may be a number of examples on-line, I |
|
|
will just list one for now, others pointers welcome:</p> |
|
|
<ul> |
|
|
<li><a href="http://www.xml101.com:8081/dtd/">XML-101 DTD</a></li> |
|
|
</ul> |
|
|
|
|
|
<p>I suggest looking at the examples found under test/valid/dtd and any of |
|
|
the large number of books available on XML. The dia example in test/valid |
|
|
should be both simple and complete enough to allow you to build your own.</p> |

<h3><a name="General3">General overview</a></h3> |
|
|
|
|
|
<p>The module <code><a |
|
|
href="http://xmlsoft.org/html/libxml-xmlmemory.html">xmlmemory.h</a></code> |
|
|
provides the interfaces to the libxml2 memory system:</p> |
|
|
<ul> |
|
|
<li>libxml2 does not use the libc memory allocator directly but xmlFree(), |
|
|
xmlMalloc() and xmlRealloc()</li> |
|
|
<li>those routines can be reallocated to a specific set of routine, by |
|
|
default the libc ones i.e. free(), malloc() and realloc()</li> |
|
|
<li>the xmlmemory.c module includes a set of debugging routine</li> |
|
|
</ul> |
|
|
|
|
|
<h3><a name="setting">Setting libxml2 set of memory routines</a></h3> |
|
|
|
|
|
<p>It is sometimes useful to not use the default memory allocator, either for |
|
|
debugging, analysis or to implement a specific behaviour on memory management |
|
|
(like on embedded systems). Two function calls are available to do so:</p> |
|
|
<ul> |
|
|
<li><a href="http://xmlsoft.org/html/libxml-xmlmemory.html">xmlMemGet |
|
|
()</a> which return the current set of functions in use by the parser</li> |
|
|
<li><a |
|
|
href="http://xmlsoft.org/html/libxml-xmlmemory.html">xmlMemSetup()</a> |
|
|
which allow to set up a new set of memory allocation functions</li> |
|
|
</ul> |
|
|
|
|
|
<p>Of course a call to xmlMemSetup() should probably be done before calling |
|
|
any other libxml2 routines (unless you are sure your allocations routines are |
|
|
compatibles).</p> |
|
|
|
|
|
<h3><a name="cleanup">Cleaning up after using the library</a></h3> |
|
|
|
|
|
<p>Libxml2 is not stateless, there is a few set of memory structures needing |
|
|
allocation before the parser is fully functional (some encoding structures |
|
|
for example). This also mean that once parsing is finished there is a tiny |
|
|
amount of memory (a few hundred bytes) which can be recollected if you don't |
|
|
reuse the library or any document built with it:</p> |
|
|
<ul> |
|
|
<li><a href="http://xmlsoft.org/html/libxml-parser.html">xmlCleanupParser |
|
|
()</a> is a centralized routine to free the library state and data. Note |
|
|
that it won't deallocate any produced tree if any (use the xmlFreeDoc() |
|
|
and related routines for this). This should be called only when the library |
|
|
is not used anymore.</li> |
|
|
<li><a href="http://xmlsoft.org/html/libxml-parser.html">xmlInitParser |
|
|
()</a> is the dual routine allowing to preallocate the parsing state |
|
|
which can be useful for example to avoid initialization reentrancy |
|
|
problems when using libxml2 in multithreaded applications</li> |
|
|
</ul> |
|
|
|
|
|
<p>Generally xmlCleanupParser() is safe assuming no parsing is ongoing and |
|
|
no document is still being used, if needed the state will be rebuild at the |
|
|
next invocation of parser routines (or by xmlInitParser()), but be careful |
|
|
of the consequences in multithreaded applications.</p> |
|
|
|
|
|
<h3><a name="Debugging">Debugging routines</a></h3> |
|
|
|
|
|
<p>When configured using --with-mem-debug flag (off by default), libxml2 uses |
|
|
a set of memory allocation debugging routines keeping track of all allocated |
|
|
blocks and the location in the code where the routine was called. A couple of |
|
|
other debugging routines allow to dump the memory allocated infos to a file |
|
|
or call a specific routine when a given block number is allocated:</p> |
|
|
<ul> |
|
|
<li><a |
|
|
href="http://xmlsoft.org/html/libxml-xmlmemory.html">xmlMallocLoc()</a> |
|
|
<a |
|
|
href="http://xmlsoft.org/html/libxml-xmlmemory.html">xmlReallocLoc()</a> |
|
|
and <a |
|
|
href="http://xmlsoft.org/html/libxml-xmlmemory.html">xmlMemStrdupLoc()</a> |
|
|
are the memory debugging replacement allocation routines</li> |
|
|
<li><a href="http://xmlsoft.org/html/libxml-xmlmemory.html">xmlMemoryDump |
|
|
()</a> dumps all the information about the allocated memory block lefts |
|
|
in the <code>.memdump</code> file</li> |
|
|
</ul> |
|
|
|
|
|
<p>When developing libxml2 memory debug is enabled, the tests programs call |
|
|
xmlMemoryDump () and the "make test" regression tests will check for any |
|
|
memory leak during the full regression test sequence, this helps a lot |
|
|
ensuring that libxml2 does not leak memory and bullet proof memory |
|
|
allocations use (some libc implementations are known to be far too permissive |
|
|
resulting in major portability problems!).</p> |
|
|
|
|
|
<p>If the .memdump reports a leak, it displays the allocation function and |
|
|
also tries to give some information about the content and structure of the |
|
|
allocated blocks left. This is sufficient in most cases to find the culprit, |
|
|
but not always. Assuming the allocation problem is reproducible, it is |
|
|
possible to find more easily:</p> |
|
|
<ol> |
|
|
<li>write down the block number xxxx not allocated</li> |
|
|
<li>export the environment variable XML_MEM_BREAKPOINT=xxxx , the easiest |
|
|
when using GDB is to simply give the command |
|
|
<p><code>set environment XML_MEM_BREAKPOINT xxxx</code></p> |
|
|
<p>before running the program.</p> |
|
|
</li> |
|
|
<li>run the program under a debugger and set a breakpoint on |
|
|
xmlMallocBreakpoint() a specific function called when this precise block |
|
|
is allocated</li> |
|
|
<li>when the breakpoint is reached you can then do a fine analysis of the |
|
|
allocation an step to see the condition resulting in the missing |
|
|
deallocation.</li> |
|
|
</ol> |
|
|
|
|
|
<p>I used to use a commercial tool to debug libxml2 memory problems but after |
|
|
noticing that it was not detecting memory leaks that simple mechanism was |
|
|
used and proved extremely efficient until now. Lately I have also used <a |
|
|
href="http://developer.kde.org/~sewardj/">valgrind</a> with quite some |
|
|
success, it is tied to the i386 architecture since it works by emulating the |
|
|
processor and instruction set, it is slow but extremely efficient, i.e. it |
|
|
spot memory usage errors in a very precise way.</p> |
|
|
|
|
|
<h3><a name="General4">General memory requirements</a></h3> |
|
|
|
|
|
<p>How much libxml2 memory require ? It's hard to tell in average it depends |
|
|
of a number of things:</p> |
|
|
<ul> |
|
|
<li>the parser itself should work in a fixed amount of memory, except for |
|
|
information maintained about the stacks of names and entities locations. |
|
|
The I/O and encoding handlers will probably account for a few KBytes. |
|
|
This is true for both the XML and HTML parser (though the HTML parser |
|
|
need more state).</li> |
|
|
<li>If you are generating the DOM tree then memory requirements will grow |
|
|
nearly linear with the size of the data. In general for a balanced |
|
|
textual document the internal memory requirement is about 4 times the |
|
|
size of the UTF8 serialization of this document (example the XML-1.0 |
|
|
recommendation is a bit more of 150KBytes and takes 650KBytes of main |
|
|
memory when parsed). Validation will add a amount of memory required for |
|
|
maintaining the external Dtd state which should be linear with the |
|
|
complexity of the content model defined by the Dtd</li> |
|
|
<li>If you need to work with fixed memory requirements or don't need the |
|
|
full DOM tree then using the <a href="xmlreader.html">xmlReader |
|
|
interface</a> is probably the best way to proceed, it still allows to |
|
|
validate or operate on subset of the tree if needed.</li> |
|
|
<li>If you don't care about the advanced features of libxml2 like |
|
|
validation, DOM, XPath or XPointer, don't use entities, need to work with |
|
|
fixed memory requirements, and try to get the fastest parsing possible |
|
|
then the SAX interface should be used, but it has known restrictions.</li> |
|
|
</ul> |
|
|
|
|
|
<p></p> |
|
|
<h3><a name="Compacting">Returning memory to the kernel</a></h3> |
|
|
|
|
|
<p>You may encounter that your process using libxml2 does not have a |
|
|
reduced memory usage although you freed the trees. This is because |
|
|
libxml2 allocates memory in a number of small chunks. When freeing one |
|
|
of those chunks, the OS may decide that giving this little memory back |
|
|
to the kernel will cause too much overhead and delay the operation. As |
|
|
all chunks are this small, they get actually freed but not returned to |
|
|
the kernel. On systems using glibc, there is a function call |
|
|
"malloc_trim" from malloc.h which does this missing operation (note that |
|
|
it is allowed to fail). Thus, after freeing your tree you may simply try |
|
|
"malloc_trim(0);" to really get the memory back. If your OS does not |
|
|
provide malloc_trim, try searching for a similar function.</p> |

<h3><a name="What">What does internationalization support mean ?</a></h3> |
|
|
|
|
|
<p>XML was designed from the start to allow the support of any character set |
|
|
by using Unicode. Any conformant XML parser has to support the UTF-8 and |
|
|
UTF-16 default encodings which can both express the full unicode ranges. UTF8 |
|
|
is a variable length encoding whose greatest points are to reuse the same |
|
|
encoding for ASCII and to save space for Western encodings, but it is a bit |
|
|
more complex to handle in practice. UTF-16 use 2 bytes per character (and |
|
|
sometimes combines two pairs), it makes implementation easier, but looks a |
|
|
bit overkill for Western languages encoding. Moreover the XML specification |
|
|
allows the document to be encoded in other encodings at the condition that |
|
|
they are clearly labeled as such. For example the following is a wellformed |
|
|
XML document encoded in ISO-8859-1 and using accentuated letters that we |
|
|
French like for both markup and content:</p> |
|
|
<pre><?xml version="1.0" encoding="ISO-8859-1"?> |
|
|
<très>là </très></pre> |
|
|
|
|
|
<p>Having internationalization support in libxml2 means the following:</p> |
|
|
<ul> |
|
|
<li>the document is properly parsed</li> |
|
|
<li>information about it's encoding is saved</li> |
|
|
<li>it can be modified</li> |
|
|
<li>it can be saved in its original encoding</li> |
|
|
<li>it can also be saved in another encoding supported by libxml2 (for |
|
|
example straight UTF8 or even an ASCII form)</li> |
|
|
</ul> |
|
|
|
|
|
<p>Another very important point is that the whole libxml2 API, with the |
|
|
exception of a few routines to read with a specific encoding or save to a |
|
|
specific encoding, is completely agnostic about the original encoding of the |
|
|
document.</p> |
|
|
|
|
|
<p>It should be noted too that the HTML parser embedded in libxml2 now obey |
|
|
the same rules too, the following document will be (as of 2.2.2) handled in |
|
|
an internationalized fashion by libxml2 too:</p> |

<h3><a name="internal">The internal encoding, how and why</a></h3> |
|
|
|
|
|
<p>One of the core decisions was to force all documents to be converted to a |
|
|
default internal encoding, and that encoding to be UTF-8, here are the |
|
|
rationales for those choices:</p> |
|
|
<ul> |
|
|
<li>keeping the native encoding in the internal form would force the libxml |
|
|
users (or the code associated) to be fully aware of the encoding of the |
|
|
original document, for examples when adding a text node to a document, |
|
|
the content would have to be provided in the document encoding, i.e. the |
|
|
client code would have to check it before hand, make sure it's conformant |
|
|
to the encoding, etc ... Very hard in practice, though in some specific |
|
|
cases this may make sense.</li> |
|
|
<li>the second decision was which encoding. From the XML spec only UTF8 and |
|
|
UTF16 really makes sense as being the two only encodings for which there |
|
|
is mandatory support. UCS-4 (32 bits fixed size encoding) could be |
|
|
considered an intelligent choice too since it's a direct Unicode mapping |
|
|
support. I selected UTF-8 on the basis of efficiency and compatibility |
|
|
with surrounding software: |
|
|
<ul> |
|
|
<li>UTF-8 while a bit more complex to convert from/to (i.e. slightly |
|
|
more costly to import and export CPU wise) is also far more compact |
|
|
than UTF-16 (and UCS-4) for a majority of the documents I see it used |
|
|
for right now (RPM RDF catalogs, advogato data, various configuration |
|
|
file formats, etc.) and the key point for today's computer |
|
|
architecture is efficient uses of caches. If one nearly double the |
|
|
memory requirement to store the same amount of data, this will trash |
|
|
caches (main memory/external caches/internal caches) and my take is |
|
|
that this harms the system far more than the CPU requirements needed |
|
|
for the conversion to UTF-8</li> |
|
|
<li>Most of libxml2 version 1 users were using it with straight ASCII |
|
|
most of the time, doing the conversion with an internal encoding |
|
|
requiring all their code to be rewritten was a serious show-stopper |
|
|
for using UTF-16 or UCS-4.</li> |
|
|
<li>UTF-8 is being used as the de-facto internal encoding standard for |
|
|
related code like the <a href="http://www.pango.org/">pango</a> |
|
|
upcoming Gnome text widget, and a lot of Unix code (yet another place |
|
|
where Unix programmer base takes a different approach from Microsoft |
|
|
- they are using UTF-16)</li> |
|
|
</ul> |
|
|
</li> |
|
|
</ul> |
|
|
|
|
|
<p>What does this mean in practice for the libxml2 user:</p> |
|
|
<ul> |
|
|
<li>xmlChar, the libxml2 data type is a byte, those bytes must be assembled |
|
|
as UTF-8 valid strings. The proper way to terminate an xmlChar * string |
|
|
is simply to append 0 byte, as usual.</li> |
|
|
<li>One just need to make sure that when using chars outside the ASCII set, |
|
|
the values has been properly converted to UTF-8</li> |
|
|
</ul> |
|
|
|
|
|
<h3><a name="implemente">How is it implemented ?</a></h3> |
|
|
|
|
|
<p>Let's describe how all this works within libxml, basically the I18N |
|
|
(internationalization) support get triggered only during I/O operation, i.e. |
|
|
when reading a document or saving one. Let's look first at the reading |
|
|
sequence:</p> |
|
|
<ol> |
|
|
<li>when a document is processed, we usually don't know the encoding, a |
|
|
simple heuristic allows to detect UTF-16 and UCS-4 from encodings where |
|
|
the ASCII range (0-0x7F) maps with ASCII</li> |
|
|
<li>the xml declaration if available is parsed, including the encoding |
|
|
declaration. At that point, if the autodetected encoding is different |
|
|
from the one declared a call to xmlSwitchEncoding() is issued.</li> |
|
|
<li>If there is no encoding declaration, then the input has to be in either |
|
|
UTF-8 or UTF-16, if it is not then at some point when processing the |
|
|
input, the converter/checker of UTF-8 form will raise an encoding error. |
|
|
You may end-up with a garbled document, or no document at all ! Example: |
|
|
<pre>~/XML -> ./xmllint err.xml |
|
|
err.xml:1: error: Input is not proper UTF-8, indicate encoding ! |
|
|
<très>là </très> |
|
|
^ |
|
|
err.xml:1: error: Bytes: 0xE8 0x73 0x3E 0x6C |
|
|
<très>là </très> |
|
|
^</pre> |
|
|
</li> |
|
|
<li>xmlSwitchEncoding() does an encoding name lookup, canonicalize it, and |
|
|
then search the default registered encoding converters for that encoding. |
|
|
If it's not within the default set and iconv() support has been compiled |
|
|
it, it will ask iconv for such an encoder. If this fails then the parser |
|
|
will report an error and stops processing: |
|
|
<pre>~/XML -> ./xmllint err2.xml |
|
|
err2.xml:1: error: Unsupported encoding UnsupportedEnc |
|
|
<?xml version="1.0" encoding="UnsupportedEnc"?> |
|
|
^</pre> |
|
|
</li> |
|
|
<li>From that point the encoder processes progressively the input (it is |
|
|
plugged as a front-end to the I/O module) for that entity. It captures |
|
|
and converts on-the-fly the document to be parsed to UTF-8. The parser |
|
|
itself just does UTF-8 checking of this input and process it |
|
|
transparently. The only difference is that the encoding information has |
|
|
been added to the parsing context (more precisely to the input |
|
|
corresponding to this entity).</li> |
|
|
<li>The result (when using DOM) is an internal form completely in UTF-8 |
|
|
with just an encoding information on the document node.</li> |
|
|
</ol> |
|
|
|
|
|
<p>Ok then what happens when saving the document (assuming you |
|
|
collected/built an xmlDoc DOM like structure) ? It depends on the function |
|
|
called, xmlSaveFile() will just try to save in the original encoding, while |
|
|
xmlSaveFileTo() and xmlSaveFileEnc() can optionally save to a given |
|
|
encoding:</p> |
|
|
<ol> |
|
|
<li>if no encoding is given, libxml2 will look for an encoding value |
|
|
associated to the document and if it exists will try to save to that |
|
|
encoding, |
|
|
<p>otherwise everything is written in the internal form, i.e. UTF-8</p> |
|
|
</li> |
|
|
<li>so if an encoding was specified, either at the API level or on the |
|
|
document, libxml2 will again canonicalize the encoding name, lookup for a |
|
|
converter in the registered set or through iconv. If not found the |
|
|
function will return an error code</li> |
|
|
<li>the converter is placed before the I/O buffer layer, as another kind of |
|
|
buffer, then libxml2 will simply push the UTF-8 serialization to through |
|
|
that buffer, which will then progressively be converted and pushed onto |
|
|
the I/O layer.</li> |
|
|
<li>It is possible that the converter code fails on some input, for example |
|
|
trying to push an UTF-8 encoded Chinese character through the UTF-8 to |
|
|
ISO-8859-1 converter won't work. Since the encoders are progressive they |
|
|
will just report the error and the number of bytes converted, at that |
|
|
point libxml2 will decode the offending character, remove it from the |
|
|
buffer and replace it with the associated charRef encoding &#123; and |
|
|
resume the conversion. This guarantees that any document will be saved |
|
|
without losses (except for markup names where this is not legal, this is |
|
|
a problem in the current version, in practice avoid using non-ascii |
|
|
characters for tag or attribute names). A special "ascii" encoding name |
|
|
is used to save documents to a pure ascii form can be used when |
|
|
portability is really crucial</li> |
|
|
</ol> |
|
|
|
|
|
<p>Here are a few examples based on the same test document and assumin a |
|
|
terminal using ISO-8859-1 as the text encoding:</p> |
|
|
<pre>~/XML -> ./xmllint isolat1 |
|
|
<?xml version="1.0" encoding="ISO-8859-1"?> |
|
|
<très>là </très> |
|
|
~/XML -> ./xmllint --encode UTF-8 isolat1 |
|
|
<?xml version="1.0" encoding="UTF-8"?> |
|
|
<très>là </très> |
|
|
~/XML -> </pre> |
|
|
|
|
|
<p>The same processing is applied (and reuse most of the code) for HTML I18N |
|
|
processing. Looking up and modifying the content encoding is a bit more |
|
|
difficult since it is located in a <meta> tag under the <head>, |
|
|
so a couple of functions htmlGetMetaEncoding() and htmlSetMetaEncoding() have |
|
|
been provided. The parser also attempts to switch encoding on the fly when |
|
|
detecting such a tag on input. Except for that the processing is the same |
|
|
(and again reuses the same code).</p> |
|
|
|
|
|
<h3><a name="Default">Default supported encodings</a></h3> |
|
|
|
|
|
<p>libxml2 has a set of default converters for the following encodings |
|
|
(located in encoding.c):</p> |
|
|
<ol> |
|
|
<li>UTF-8 is supported by default (null handlers)</li> |
|
|
<li>UTF-16, both little and big endian</li> |
|
|
<li>ISO-Latin-1 (ISO-8859-1) covering most western languages</li> |
|
|
<li>ASCII, useful mostly for saving</li> |
|
|
<li>HTML, a specific handler for the conversion of UTF-8 to ASCII with HTML |
|
|
predefined entities like &copy; for the Copyright sign.</li> |
|
|
</ol> |
|
|
|
|
|
<p>More over when compiled on an Unix platform with iconv support the full |
|
|
set of encodings supported by iconv can be instantly be used by libxml. On a |
|
|
linux machine with glibc-2.1 the list of supported encodings and aliases fill |
|
|
3 full pages, and include UCS-4, the full set of ISO-Latin encodings, and the |
|
|
various Japanese ones.</p> |
|
|
|
|
|
<p>To convert from the UTF-8 values returned from the API to another encoding |
|
|
then it is possible to use the function provided from <a |
|
|
href="html/libxml-encoding.html">the encoding module</a> like <a |
|
|
href="html/libxml-encoding.html#UTF8Toisolat1">UTF8Toisolat1</a>, or use the |
|
|
POSIX <a |
|
|
href="http://www.opengroup.org/onlinepubs/009695399/functions/iconv.html">iconv()</a> |
|
|
API directly.</p> |
|
|
|
|
|
<h4>Encoding aliases</h4> |
|
|
|
|
|
<p>From 2.2.3, libxml2 has support to register encoding names aliases. The |
|
|
goal is to be able to parse document whose encoding is supported but where |
|
|
the name differs (for example from the default set of names accepted by |
|
|
iconv). The following functions allow to register and handle new aliases for |
|
|
existing encodings. Once registered libxml2 will automatically lookup the |
|
|
aliases when handling a document:</p> |
|
|
<ul> |
|
|
<li>int xmlAddEncodingAlias(const char *name, const char *alias);</li> |
|
|
<li>int xmlDelEncodingAlias(const char *alias);</li> |
|
|
<li>const char * xmlGetEncodingAlias(const char *alias);</li> |
|
|
<li>void xmlCleanupEncodingAliases(void);</li> |
|
|
</ul> |
|
|
|
|
|
<h3><a name="extend">How to extend the existing support</a></h3> |
|
|
|
|
|
<p>Well adding support for new encoding, or overriding one of the encoders |
|
|
(assuming it is buggy) should not be hard, just write input and output |
|
|
conversion routines to/from UTF-8, and register them using |
|
|
xmlNewCharEncodingHandler(name, xxxToUTF8, UTF8Toxxx), and they will be |
|
|
called automatically if the parser(s) encounter such an encoding name |
|
|
(register it uppercase, this will help). The description of the encoders, |
|
|
their arguments and expected return values are described in the encoding.h |
|
|
header.</p> |

<h3><a name="General1">General overview</a></h3> |
|
|
|
|
|
<p>The module <code><a |
|
|
href="http://xmlsoft.org/html/libxml-xmlio.html">xmlIO.h</a></code> provides |
|
|
the interfaces to the libxml2 I/O system. This consists of 4 main parts:</p> |
|
|
<ul> |
|
|
<li>Entities loader, this is a routine which tries to fetch the entities |
|
|
(files) based on their PUBLIC and SYSTEM identifiers. The default loader |
|
|
don't look at the public identifier since libxml2 do not maintain a |
|
|
catalog. You can redefine you own entity loader by using |
|
|
<code>xmlGetExternalEntityLoader()</code> and |
|
|
<code>xmlSetExternalEntityLoader()</code>. <a href="#entities">Check the |
|
|
example</a>.</li> |
|
|
<li>Input I/O buffers which are a commodity structure used by the parser(s) |
|
|
input layer to handle fetching the information to feed the parser. This |
|
|
provides buffering and is also a placeholder where the encoding |
|
|
converters to UTF8 are piggy-backed.</li> |
|
|
<li>Output I/O buffers are similar to the Input ones and fulfill similar |
|
|
task but when generating a serialization from a tree.</li> |
|
|
<li>A mechanism to register sets of I/O callbacks and associate them with |
|
|
specific naming schemes like the protocol part of the URIs. |
|
|
<p>This affect the default I/O operations and allows to use specific I/O |
|
|
handlers for certain names.</p> |
|
|
</li> |
|
|
</ul> |
|
|
|
|
|
<p>The general mechanism used when loading http://rpmfind.net/xml.html for |
|
|
example in the HTML parser is the following:</p> |
|
|
<ol> |
|
|
<li>The default entity loader calls <code>xmlNewInputFromFile()</code> with |
|
|
the parsing context and the URI string.</li> |
|
|
<li>the URI string is checked against the existing registered handlers |
|
|
using their match() callback function, if the HTTP module was compiled |
|
|
in, it is registered and its match() function will succeeds</li> |
|
|
<li>the open() function of the handler is called and if successful will |
|
|
return an I/O Input buffer</li> |
|
|
<li>the parser will the start reading from this buffer and progressively |
|
|
fetch information from the resource, calling the read() function of the |
|
|
handler until the resource is exhausted</li> |
|
|
<li>if an encoding change is detected it will be installed on the input |
|
|
buffer, providing buffering and efficient use of the conversion |
|
|
routines</li> |
|
|
<li>once the parser has finished, the close() function of the handler is |
|
|
called once and the Input buffer and associated resources are |
|
|
deallocated.</li> |
|
|
</ol> |
|
|
|
|
|
<p>The user defined callbacks are checked first to allow overriding of the |
|
|
default libxml2 I/O routines.</p> |
|
|
|
|
|
<h3><a name="basic">The basic buffer type</a></h3> |
|
|
|
|
|
<p>All the buffer manipulation handling is done using the |
|
|
<code>xmlBuffer</code> type define in <code><a |
|
|
href="http://xmlsoft.org/html/libxml-tree.html">tree.h</a> </code>which is a |
|
|
resizable memory buffer. The buffer allocation strategy can be selected to be |
|
|
either best-fit or use an exponential doubling one (CPU vs. memory use |
|
|
trade-off). The values are <code>XML_BUFFER_ALLOC_EXACT</code> and |
|
|
<code>XML_BUFFER_ALLOC_DOUBLEIT</code>, and can be set individually or on a |
|
|
system wide basis using <code>xmlBufferSetAllocationScheme()</code>. A number |
|
|
of functions allows to manipulate buffers with names starting with the |
|
|
<code>xmlBuffer...</code> prefix.</p> |
|
|
|
|
|
<h3><a name="Input">Input I/O handlers</a></h3> |
|
|
|
|
|
<p>An Input I/O handler is a simple structure |
|
|
<code>xmlParserInputBuffer</code> containing a context associated to the |
|
|
resource (file descriptor, or pointer to a protocol handler), the read() and |
|
|
close() callbacks to use and an xmlBuffer. And extra xmlBuffer and a charset |
|
|
encoding handler are also present to support charset conversion when |
|
|
needed.</p> |
|
|
|
|
|
<h3><a name="Output">Output I/O handlers</a></h3> |
|
|
|
|
|
<p>An Output handler <code>xmlOutputBuffer</code> is completely similar to an |
|
|
Input one except the callbacks are write() and close().</p> |
|
|
|
|
|
<h3><a name="entities">The entities loader</a></h3> |
|
|
|
|
|
<p>The entity loader resolves requests for new entities and create inputs for |
|
|
the parser. Creating an input from a filename or an URI string is done |
|
|
through the xmlNewInputFromFile() routine. The default entity loader do not |
|
|
handle the PUBLIC identifier associated with an entity (if any). So it just |
|
|
calls xmlNewInputFromFile() with the SYSTEM identifier (which is mandatory in |
|
|
XML).</p> |
|
|
|
|
|
<p>If you want to hook up a catalog mechanism then you simply need to |
|
|
override the default entity loader, here is an example:</p> |
|
|
<pre>#include <libxml/xmlIO.h> |
|
|
|
|
|
xmlExternalEntityLoader defaultLoader = NULL; |
|
|
|
|
|
xmlParserInputPtr |
|
|
xmlMyExternalEntityLoader(const char *URL, const char *ID, |
|
|
xmlParserCtxtPtr ctxt) { |
|
|
xmlParserInputPtr ret; |
|
|
const char *fileID = NULL; |
|
|
/* lookup for the fileID depending on ID */ |
|
|
|
|
|
ret = xmlNewInputFromFile(ctxt, fileID); |
|
|
if (ret != NULL) |
|
|
return(ret); |
|
|
if (defaultLoader != NULL) |
|
|
ret = defaultLoader(URL, ID, ctxt); |
|
|
return(ret); |
|
|
} |
|
|
|
|
|
int main(..) { |
|
|
... |
|
|
|
|
|
/* |
|
|
* Install our own entity loader |
|
|
*/ |
|
|
defaultLoader = xmlGetExternalEntityLoader(); |
|
|
xmlSetExternalEntityLoader(xmlMyExternalEntityLoader); |
|
|
|
|
|
... |
|
|
}</pre> |
|
|
|
|
|
<h3><a name="Example2">Example of customized I/O</a></h3> |
|
|
|
|
|
<p>This example come from <a href="http://xmlsoft.org/messages/0708.html">a |
|
|
real use case</a>, xmlDocDump() closes the FILE * passed by the application |
|
|
and this was a problem. The <a |
|
|
href="http://xmlsoft.org/messages/0711.html">solution</a> was to redefine a |
|
|
new output handler with the closing call deactivated:</p> |
|
|
<ol> |
|
|
<li>First define a new I/O output allocator where the output don't close |
|
|
the file: |
|
|
<pre>xmlOutputBufferPtr |
|
|
xmlOutputBufferCreateOwn(FILE *file, xmlCharEncodingHandlerPtr encoder) { |
|
|
xmlOutputBufferPtr ret; |
|
|
|
|
|
if (xmlOutputCallbackInitialized == 0) |
|
|
xmlRegisterDefaultOutputCallbacks(); |
|
|
|
|
|
if (file == NULL) return(NULL); |
|
|
ret = xmlAllocOutputBuffer(encoder); |
|
|
if (ret != NULL) { |
|
|
ret->context = file; |
|
|
ret->writecallback = xmlFileWrite; |
|
|
ret->closecallback = NULL; /* No close callback */ |
|
|
} |
|
|
return(ret); |
|
|
} </pre> |
|
|
</li> |
|
|
<li>And then use it to save the document: |
|
|
<pre>FILE *f; |
|
|
xmlOutputBufferPtr output; |
|
|
xmlDocPtr doc; |
|
|
int res; |
|
|
|
|
|
f = ... |
|
|
doc = .... |
|
|
|
|
|
output = xmlOutputBufferCreateOwn(f, NULL); |
|
|
res = xmlSaveFileTo(output, doc, NULL); |
|
|
</pre> |

<h3><a name="General2">General overview</a></h3> |
|
|
|
|
|
<p>What is a catalog? Basically it's a lookup mechanism used when an entity |
|
|
(a file or a remote resource) references another entity. The catalog lookup |
|
|
is inserted between the moment the reference is recognized by the software |
|
|
(XML parser, stylesheet processing, or even images referenced for inclusion |
|
|
in a rendering) and the time where loading that resource is actually |
|
|
started.</p> |
|
|
|
|
|
<p>It is basically used for 3 things:</p> |
|
|
<ul> |
|
|
<li>mapping from "logical" names, the public identifiers and a more |
|
|
concrete name usable for download (and URI). For example it can associate |
|
|
the logical name |
|

<h3><a name="definition">The definitions</a></h3> |

|
|
|
<p>Libxml, as of 2.4.3 implements 2 kind of catalogs:</p> |
|
|
<ul> |
|
|
<li>the older SGML catalogs, the official spec is SGML Open Technical |
|
|
Resolution TR9401:1997, but is better understood by reading <a |
|
|
href="http://www.jclark.com/sp/catalog.htm">the SP Catalog page</a> from |
|
|
James Clark. This is relatively old and not the preferred mode of |
|
|
operation of libxml.</li> |
|
|
<li><a href="http://www.oasis-open.org/committees/entity/spec.html">XML |
|
|
Catalogs</a> is far more flexible, more recent, uses an XML syntax and |
|
|
should scale quite better. This is the default option of libxml.</li> |

<h3><a name="Simple">Using catalog</a></h3> |
|
|
|
|
|
<p>In a normal environment libxml2 will by default check the presence of a |
|
|
catalog in /etc/xml/catalog, and assuming it has been correctly populated, |
|
|
the processing is completely transparent to the document user. To take a |
|
|
concrete example, suppose you are authoring a DocBook document, this one |
|
|
starts with the following DOCTYPE definition:</p> |
|
|
<pre><?xml version='1.0'?> |
|
|
<!DOCTYPE book PUBLIC "-//Norman Walsh//DTD DocBk XML V3.1.4//EN" |
|
|
"http://nwalsh.com/docbook/xml/3.1.4/db3xml.dtd"></pre> |
|
|
|
|
|
<p>When validating the document with libxml, the catalog will be |
|
|
automatically consulted to lookup the public identifier "-//Norman Walsh//DTD |
|
|
DocBk XML V3.1.4//EN" and the system identifier |
|
|
"http://nwalsh.com/docbook/xml/3.1.4/db3xml.dtd", and if these entities have |
|
|
been installed on your system and the catalogs actually point to them, libxml |
|
|
will fetch them from the local disk.</p> |
|
|
|
|
|
<p style="font-size: 10pt"><strong>Note</strong>: Really don't use this |
|
|
DOCTYPE example it's a really old version, but is fine as an example.</p> |
|
|
|
|
|
<p>Libxml2 will check the catalog each time that it is requested to load an |
|
|
entity, this includes DTD, external parsed entities, stylesheets, etc ... If |
|
|
your system is correctly configured all the authoring phase and processing |
|
|
should use only local files, even if your document stays portable because it |
|
|
uses the canonical public and system ID, referencing the remote document.</p> |
|
|
|
|
|
<h3><a name="Some">Some examples:</a></h3> |
|
|
|
|
|
<p>Here is a couple of fragments from XML Catalogs used in libxml2 early |
|
|
regression tests in <code>test/catalogs</code> :</p> |
|
|
<pre><?xml version="1.0"?> |
|
|
<!DOCTYPE catalog PUBLIC |
|
|
"-//OASIS//DTD Entity Resolution XML Catalog V1.0//EN" |
|
|
"http://www.oasis-open.org/committees/entity/release/1.0/catalog.dtd"> |
|
|
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"> |
|
|
<public publicId="-//OASIS//DTD DocBook XML V4.1.2//EN" |
|
|
uri="http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd"/> |
|
|
...</pre> |
|
|
|
|
|
<p>This is the beginning of a catalog for DocBook 4.1.2, XML Catalogs are |
|
|
written in XML, there is a specific namespace for catalog elements |
|
|
"urn:oasis:names:tc:entity:xmlns:xml:catalog". The first entry in this |
|
|
catalog is a <code>public</code> mapping it allows to associate a Public |
|
|
Identifier with an URI.</p> |
|
|
<pre>... |
|
|
<rewriteSystem systemIdStartString="http://www.oasis-open.org/docbook/" |
|
|
rewritePrefix="file:///usr/share/xml/docbook/"/> |
|
|
...</pre> |
|
|
|
|
|
<p>A <code>rewriteSystem</code> is a very powerful instruction, it says that |
|
|
any URI starting with a given prefix should be looked at another URI |
|
|
constructed by replacing the prefix with an new one. In effect this acts like |
|
|
a cache system for a full area of the Web. In practice it is extremely useful |
|
|
with a file prefix if you have installed a copy of those resources on your |
|
|
local system.</p> |
|
|
<pre>... |
|
|
<delegatePublic publicIdStartString="-//OASIS//DTD XML Catalog //" |
|
|
catalog="file:///usr/share/xml/docbook.xml"/> |
|
|
<delegatePublic publicIdStartString="-//OASIS//ENTITIES DocBook XML" |
|

|
|
<delegateURI uriStartString="http://www.oasis-open.org/docbook/" |
|
|
catalog="file:///usr/share/xml/docbook.xml"/> |
|
|
...</pre> |
|
|
|
|
|
<p>Delegation is the core features which allows to build a tree of catalogs, |
|
|
easier to maintain than a single catalog, based on Public Identifier, System |
|
|
Identifier or URI prefixes it instructs the catalog software to look up |
|
|
entries in another resource. This feature allow to build hierarchies of |
|
|
catalogs, the set of entries presented should be sufficient to redirect the |
|
|
resolution of all DocBook references to the specific catalog in |
|
|
<code>/usr/share/xml/docbook.xml</code> this one in turn could delegate all |
|
|
references for DocBook 4.2.1 to a specific catalog installed at the same time |
|
|
as the DocBook resources on the local machine.</p> |
|
|
|
|
|
<h3><a name="reference">How to tune catalog usage:</a></h3> |
|
|
|
|
|
<p>The user can change the default catalog behaviour by redirecting queries |
|
|
to its own set of catalogs, this can be done by setting the |
|
|
<code>XML_CATALOG_FILES</code> environment variable to a list of catalogs, an |
|
|
empty one should deactivate loading the default <code>/etc/xml/catalog</code> |
|
|
default catalog</p> |
|
|
|
|
|
<h3><a name="validate">How to debug catalog processing:</a></h3> |
|
|
|
|
|
<p>Setting up the <code>XML_DEBUG_CATALOG</code> environment variable will |
|
|
make libxml2 output debugging information for each catalog operations, for |
|
|
example:</p> |
|
|
<pre>orchis:~/XML -> xmllint --memory --noout test/ent2 |
|
|
warning: failed to load external entity "title.xml" |
|
|
orchis:~/XML -> export XML_DEBUG_CATALOG= |
|
|
orchis:~/XML -> xmllint --memory --noout test/ent2 |
|
|
Failed to parse catalog /etc/xml/catalog |
|
|
Failed to parse catalog /etc/xml/catalog |
|
|
warning: failed to load external entity "title.xml" |
|
|
Catalogs cleanup |
|
|
orchis:~/XML -> </pre> |
|
|
|
|
|
<p>The test/ent2 references an entity, running the parser from memory makes |
|
|
the base URI unavailable and the the "title.xml" entity cannot be loaded. |
|
|
Setting up the debug environment variable allows to detect that an attempt is |
|
|
made to load the <code>/etc/xml/catalog</code> but since it's not present the |
|
|
resolution fails.</p> |
|
|
|
|
|
<p>But the most advanced way to debug XML catalog processing is to use the |
|
|
<strong>xmlcatalog</strong> command shipped with libxml2, it allows to load |
|
|
catalogs and make resolution queries to see what is going on. This is also |
|
|
used for the regression tests:</p> |
|
|
<pre>orchis:~/XML -> ./xmlcatalog test/catalogs/docbook.xml \ |
|
|
"-//OASIS//DTD DocBook XML V4.1.2//EN" |
|
|
http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd |
|
|
orchis:~/XML -> </pre> |
|
|
|
|
|
<p>For debugging what is going on, adding one -v flags increase the verbosity |
|
|
level to indicate the processing done (adding a second flag also indicate |
|
|
what elements are recognized at parsing):</p> |
|
|
<pre>orchis:~/XML -> ./xmlcatalog -v test/catalogs/docbook.xml \ |
|
|
"-//OASIS//DTD DocBook XML V4.1.2//EN" |
|

|
|

|
|
orchis:~/XML -> </pre> |
|
|
|
|
|
<p>A shell interface is also available to debug and process multiple queries |
|
|
(and for regression tests):</p> |
|
|
<pre>orchis:~/XML -> ./xmlcatalog -shell test/catalogs/docbook.xml \ |
|
|

used heavily to debug the XML Catalog implementation itself.</p> |

<h3><a name="Declaring">How to create and maintain</a> catalogs:</h3> |
|
|
|
|
|
<p>Basically XML Catalogs are XML files, you can either use XML tools to |
|
|
manage them or use <strong>xmlcatalog</strong> for this. The basic step is |
|
|
to create a catalog the -create option provide this facility:</p> |
|
|
<pre>orchis:~/XML -> ./xmlcatalog --create tst.xml |
|
|
<?xml version="1.0"?> |
|
|
<!DOCTYPE catalog PUBLIC "-//OASIS//DTD Entity Resolution XML Catalog V1.0//EN" |
|
|
"http://www.oasis-open.org/committees/entity/release/1.0/catalog.dtd"> |
|
|
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"/> |
|
|
orchis:~/XML -> </pre> |
|
|
|
|
|
<p>By default xmlcatalog does not overwrite the original catalog and save the |
|
|
result on the standard output, this can be overridden using the -noout |
|
|
option. The <code>-add</code> command allows to add entries in the |
|
|
catalog:</p> |
|
|
<pre>orchis:~/XML -> ./xmlcatalog --noout --create --add "public" \ |
|
|
"-//OASIS//DTD DocBook XML V4.1.2//EN" \ |
|
|
http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd tst.xml |
|
|
orchis:~/XML -> cat tst.xml |
|
|
<?xml version="1.0"?> |
|
|
<!DOCTYPE catalog PUBLIC "-//OASIS//DTD Entity Resolution XML Catalog V1.0//EN" \ |
|
|
"http://www.oasis-open.org/committees/entity/release/1.0/catalog.dtd"> |
|
|
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"> |
|
|
<public publicId="-//OASIS//DTD DocBook XML V4.1.2//EN" |
|
|
uri="http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd"/> |
|
|
</catalog> |
|
|
orchis:~/XML -> </pre> |
|
|
|
|
|
<p>The <code>-add</code> option will always take 3 parameters even if some of |
|
|
the XML Catalog constructs (like nextCatalog) will have only a single |
|
|
argument, just pass a third empty string, it will be ignored.</p> |
|
|
|
|
|
<p>Similarly the <code>-del</code> option remove matching entries from the |
|
|
catalog:</p> |
|
|
<pre>orchis:~/XML -> ./xmlcatalog --del \ |
|
|
"http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd" tst.xml |
|
|
<?xml version="1.0"?> |
|
|
<!DOCTYPE catalog PUBLIC "-//OASIS//DTD Entity Resolution XML Catalog V1.0//EN" |
|
|
"http://www.oasis-open.org/committees/entity/release/1.0/catalog.dtd"> |
|
|
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"/> |
|
|
orchis:~/XML -> </pre> |
|
|
|
|
|
<p>The catalog is now empty. Note that the matching of <code>-del</code> is |
|
|
exact and would have worked in a similar fashion with the Public ID |
|
|
string.</p> |
|
|
|
|
|
<p>This is rudimentary but should be sufficient to manage a not too complex |
|
|
catalog tree of resources.</p> |
|
|

|
<h3><a name="implemento">The implementor corner quick review of the |
|
|
API:</a></h3> |
|
|
|
|
|
<p>First, and like for every other module of libxml, there is an |
|
|
automatically generated <a href="html/libxml-catalog.html">API page for |
|
|
catalog support</a>.</p> |
|
|
|
|
|
<p>The header for the catalog interfaces should be included as:</p> |
|
|
<pre>#include <libxml/catalog.h></pre> |
|
|
|
|
|
<p>The API is voluntarily kept very simple. First it is not obvious that |
|
|
applications really need access to it since it is the default behaviour of |
|
|
libxml2 (Note: it is possible to completely override libxml2 default catalog |
|
|
by using <a href="html/libxml-parser.html">xmlSetExternalEntityLoader</a> to |
|
|
plug an application specific resolver).</p> |
|
|
|
|
|
<p>Basically libxml2 support 2 catalog lists:</p> |
|
|
<ul> |
|
|
<li>the default one, global shared by all the application</li> |
|
|
<li>a per-document catalog, this one is built if the document uses the |
|
|
<code>oasis-xml-catalog</code> PIs to specify its own catalog list, it is |
|
|
associated to the parser context and destroyed when the parsing context |
|
|
is destroyed.</li> |
|
|
</ul> |
|
|
|
|
|
<p>the document one will be used first if it exists.</p> |
|
|
|
|
|
<h4>Initialization routines:</h4> |
|
|
|
|
|
<p>xmlInitializeCatalog(), xmlLoadCatalog() and xmlLoadCatalogs() should be |
|
|
used at startup to initialize the catalog, if the catalog should be |
|
|
initialized with specific values xmlLoadCatalog() or xmlLoadCatalogs() |
|
|
should be called before xmlInitializeCatalog() which would otherwise do a |
|
|
default initialization first.</p> |
|
|
|
|
|
<p>The xmlCatalogAddLocal() call is used by the parser to grow the document |
|
|
own catalog list if needed.</p> |
|
|
|
|
|
<h4>Preferences setup:</h4> |
|
|
|
|
|
<p>The XML Catalog spec requires the possibility to select default |
|
|
preferences between public and system delegation, |
|
|
xmlCatalogSetDefaultPrefer() allows this, xmlCatalogSetDefaults() and |
|
|
xmlCatalogGetDefaults() allow to control if XML Catalogs resolution should |
|
|
be forbidden, allowed for global catalog, for document catalog or both, the |
|
|
default is to allow both.</p> |
|
|
|
|
|
<p>And of course xmlCatalogSetDebug() allows to generate debug messages |
|
|
(through the xmlGenericError() mechanism).</p> |
|
|
|
|
|
<h4>Querying routines:</h4> |
|
|
|
|
|
<p>xmlCatalogResolve(), xmlCatalogResolveSystem(), xmlCatalogResolvePublic() |
|
|
and xmlCatalogResolveURI() are relatively explicit if you read the XML |
|
|
Catalog specification they correspond to section 7 algorithms, they should |
|
|
also work if you have loaded an SGML catalog with a simplified semantic.</p> |
|
|
|
|
|
<p>xmlCatalogLocalResolve() and xmlCatalogLocalResolveURI() are the same but |
|
|
operate on the document catalog list</p> |
|
|
|
|
|
<h4>Cleanup and Miscellaneous:</h4> |
|
|
|
|
|
<p>xmlCatalogCleanup() free-up the global catalog, xmlCatalogFreeLocal() is |
|
|
the per-document equivalent.</p> |
|
|
|
|
|
<p>xmlCatalogAdd() and xmlCatalogRemove() are used to dynamically modify the |
|
|
first catalog in the global list, and xmlCatalogDump() allows to dump a |
|
|
catalog state, those routines are primarily designed for xmlcatalog, I'm not |
|
|
sure that exposing more complex interfaces (like navigation ones) would be |
|
|
really useful.</p> |
|
|
|
|
|
<p>The xmlParseCatalogFile() is a function used to load XML Catalog files, |
|
|
it's similar as xmlParseFile() except it bypass all catalog lookups, it's |
|
|
provided because this functionality may be useful for client tools.</p> |
|
|
|
|
|
<h4>threaded environments:</h4> |
|
|
|
|
|
<p>Since the catalog tree is built progressively, some care has been taken to |
|
|
try to avoid troubles in multithreaded environments. The code is now thread |
|
|
safe assuming that the libxml2 library has been compiled with threads |
|
|
support.</p> |
|
|
|

<h3><a name="Other">Other resources</a></h3> |
|
|
|
|
|
<p>The XML Catalog specification is relatively recent so there isn't much |
|
|
literature to point at:</p> |
|
|
<ul> |
|
|
<li>You can find a good rant from Norm Walsh about <a |
|
|
href="http://www.arbortext.com/Think_Tank/XML_Resources/Issue_Three/issue_three.html">the |
|
|
need for catalogs</a>, it provides a lot of context information even if |
|
|
I don't agree with everything presented. Norm also wrote a more recent |

the resources found on the system. Otherwise it will just create |

<h2><a name="library">The parser interfaces</a></h2> |
|
|
|
|
|
<p>This section is directly intended to help programmers getting bootstrapped |
|
|
using the XML tollkit from the C language. It is not intended to be |
|
|
extensive. I hope the automatically generated documents will provide the |
|
|
completeness required, but as a separate set of documents. The interfaces of |
|
|
the XML parser are by principle low level, Those interested in a higher level |
|
|
API should <a href="#DOM">look at DOM</a>.</p> |
|
|
|
|
|
<p>The <a href="html/libxml-parser.html">parser interfaces for XML</a> are |
|
|
separated from the <a href="html/libxml-htmlparser.html">HTML parser |
|

|

|
|
|
<h3><a name="Invoking">Invoking the parser : the pull method</a></h3> |
|
|
|
|
|
<p>Usually, the first thing to do is to read an XML input. The parser accepts |

documents either from in-memory strings or from files. The functions are |
|
|
defined in "parser.h":</p> |
|
|
<dl> |

|
<dt><code>xmlDocPtr xmlParseMemory(char *buffer, int size);</code></dt> |

|
failure).</p> |

<h3 id="Invoking1">Invoking the parser: the push method</h3> |
|
|
|
|
|
<p>In order for the application to keep the control when the document is |
|
|
being fetched (which is common for GUI based programs) libxml2 provides a |
|
|
push interface, too, as of version 1.8.3. Here are the interface |
|
|
functions:</p> |
|
|
<pre>xmlParserCtxtPtr xmlCreatePushParserCtxt(xmlSAXHandlerPtr sax, |
|
|
void *user_data, |
|
|
const char *chunk, |
|
|
int size, |
|
|
const char *filename); |
|
|
int xmlParseChunk (xmlParserCtxtPtr ctxt, |
|
|
const char *chunk, |
|
|
int size, |
|
|
int terminate);</pre> |
|
|
|
|
|
<p>and here is a simple example showing how to use the interface:</p> |
|
|
<pre> FILE *f; |
|
|
|
|
|
f = fopen(filename, "r"); |
|
|
if (f != NULL) { |
|
|
int res, size = 1024; |
|
|
char chars[1024]; |
|
|
xmlParserCtxtPtr ctxt; |
|
|
|
|
|
res = fread(chars, 1, 4, f); |
|
|
if (res > 0) { |
|
|
ctxt = xmlCreatePushParserCtxt(NULL, NULL, |
|
|
chars, res, filename); |
|
|
while ((res = fread(chars, 1, size, f)) > 0) { |
|
|
xmlParseChunk(ctxt, chars, res, 0); |
|
|
} |
|
|
xmlParseChunk(ctxt, chars, 0, 1); |
|
|
doc = ctxt->myDoc; |
|
|
xmlFreeParserCtxt(ctxt); |
|
|
} |
|
|
}</pre> |
|
|
|
|
|
<p>The HTML parser embedded into libxml2 also has a push interface; the |
|
|
functions are just prefixed by "html" rather than "xml".</p> |
|
|
|
|
|
<h3 id="Invoking2">Invoking the parser: the SAX interface</h3> |
|
|
|
|
|
<p>The tree-building interface makes the parser memory-hungry, first loading |
|
|
the document in memory and then building the tree itself. Reading a document |
|
|
without building the tree is possible using the SAX interfaces (see SAX.h and |
|
|
<a href="http://www.daa.com.au/~james/gnome/xml-sax/xml-sax.html">James |
|
|
Henstridge's documentation</a>). Note also that the push interface can be |
|
|
limited to SAX: just use the two first arguments of |
|
|
<code>xmlCreatePushParserCtxt()</code>.</p> |
|
|
|
|
|
<h3><a name="Building">Building a tree from scratch</a></h3> |
|
|
|
|
|
<p>The other way to get an XML tree in memory is by building it. Basically |
|
|
there is a set of functions dedicated to building new elements. (These are |
|
|
also described in <libxml/tree.h>.) For example, here is a piece of |
|
|
code that produces the XML document used in the previous examples:</p> |
|
|
<pre> #include <libxml/tree.h> |
|
|
xmlDocPtr doc; |
|
|
xmlNodePtr tree, subtree; |
|
|
|
|
|
doc = xmlNewDoc("1.0"); |
|
|
doc->children = xmlNewDocNode(doc, NULL, "EXAMPLE", NULL); |
|
|
xmlSetProp(doc->children, "prop1", "gnome is great"); |
|
|
xmlSetProp(doc->children, "prop2", "& linux too"); |
|
|
tree = xmlNewChild(doc->children, NULL, "head", NULL); |
|
|
subtree = xmlNewChild(tree, NULL, "title", "Welcome to Gnome"); |
|
|
tree = xmlNewChild(doc->children, NULL, "chapter", NULL); |
|
|
subtree = xmlNewChild(tree, NULL, "title", "The Linux adventure"); |
|
|
subtree = xmlNewChild(tree, NULL, "p", "bla bla bla ..."); |
|
|
subtree = xmlNewChild(tree, NULL, "image", NULL); |
|
|
xmlSetProp(subtree, "href", "linus.gif");</pre> |
|
|
|
|
|
<p>Not really rocket science ...</p> |
|
|
|
|
|
<h3><a name="Traversing">Traversing the tree</a></h3> |
|
|
|
|
|
<p>Basically by <a href="html/libxml-tree.html">including "tree.h"</a> your |
|
|
code has access to the internal structure of all the elements of the tree. |
|
|
The names should be somewhat simple like <strong>parent</strong>, |
|
|
<strong>children</strong>, <strong>next</strong>, <strong>prev</strong>, |
|
|
<strong>properties</strong>, etc... For example, still with the previous |
|
|
example:</p> |
|
|
<pre><code>doc->children->children->children</code></pre> |
|
|
|
|
|
<p>points to the title element,</p> |
|
|
<pre>doc->children->children->next->children->children</pre> |
|
|
|
|
|
<p>points to the text node containing the chapter title "The Linux |
|
|
adventure".</p> |
|
|
|
|
|
<p><strong>NOTE</strong>: XML allows <em>PI</em>s and <em>comments</em> to be |
|
|
present before the document root, so <code>doc->children</code> may point |
|
|
to an element which is not the document Root Element; a function |
|
|
<code>xmlDocGetRootElement()</code> was added for this purpose.</p> |
|
|
|
|
|
<h3><a name="Modifying">Modifying the tree</a></h3> |
|
|
|
|
|
<p>Functions are provided for reading and writing the document content. Here |
|
|
is an excerpt from the <a href="html/libxml-tree.html">tree API</a>:</p> |
|
|
<dl> |
|
|
<dt><code>xmlAttrPtr xmlSetProp(xmlNodePtr node, const xmlChar *name, const |
|
|
xmlChar *value);</code></dt> |
|
|
<dd><p>This sets (or changes) an attribute carried by an ELEMENT node. |
|
|
The value can be NULL.</p> |
|
|
</dd> |
|
|
</dl> |
|
|
<dl> |
|
|
<dt><code>const xmlChar *xmlGetProp(xmlNodePtr node, const xmlChar |
|
|
*name);</code></dt> |
|
|
<dd><p>This function returns a pointer to new copy of the property |
|
|
content. Note that the user must deallocate the result.</p> |
|
|
</dd> |
|
|
</dl> |
|
|
|
|
|
<p>Two functions are provided for reading and writing the text associated |
|
|
with elements:</p> |
|
|
<dl> |
|
|
<dt><code>xmlNodePtr xmlStringGetNodeList(xmlDocPtr doc, const xmlChar |
|
|
*value);</code></dt> |
|
|
<dd><p>This function takes an "external" string and converts it to one |
|
|
text node or possibly to a list of entity and text nodes. All |
|
|
non-predefined entity references like &Gnome; will be stored |
|
|
internally as entity nodes, hence the result of the function may not be |
|
|
a single node.</p> |
|
|
</dd> |
|
|
</dl> |
|
|
<dl> |
|
|
<dt><code>xmlChar *xmlNodeListGetString(xmlDocPtr doc, xmlNodePtr list, int |
|
|
inLine);</code></dt> |
|
|
<dd><p>This function is the inverse of |
|
|
<code>xmlStringGetNodeList()</code>. It generates a new string |
|
|
containing the content of the text and entity nodes. Note the extra |
|
|
argument inLine. If this argument is set to 1, the function will expand |
|
|
entity references. For example, instead of returning the &Gnome; |
|
|
XML encoding in the string, it will substitute it with its value (say, |
|
|
"GNU Network Object Model Environment").</p> |
|
|
</dd> |
|
|
</dl> |
|
|
|
|
|
<h3><a name="Saving">Saving a tree</a></h3> |
|
|
|
|
|
<p>Basically 3 options are possible:</p> |
|
|
<dl> |
|
|
<dt><code>void xmlDocDumpMemory(xmlDocPtr cur, xmlChar**mem, int |
|
|
*size);</code></dt> |
|

|
<h3><a name="Compressio">Compression</a></h3> |
|
|
|
|
|
<p>The library transparently handles compression when doing file-based |
|
|
accesses. The level of compression on saves can be turned on either globally |

or individually for one file:</p> |
|

<dl> |
|

|
<h2><a name="Entities">Entities or no entities</a></h2> |
|
|
|
|
|
<p>Entities in principle are similar to simple C macros. An entity defines an |
|
|
abbreviation for a given string that you can reuse many times throughout the |
|
|
content of your document. Entities are especially useful when a given string |
|
|
may occur frequently within a document, or to confine the change needed to a |
|
|
document to a restricted area in the internal subset of the document (at the |
|
|
beginning). Example:</p> |
|
|
<pre>1 <?xml version="1.0"?> |
|
|
2 <!DOCTYPE EXAMPLE SYSTEM "example.dtd" [ |
|
|
3 <!ENTITY xml "Extensible Markup Language"> |
|
|
4 ]> |
|
|
5 <EXAMPLE> |
|
|
6 &xml; |
|
|
7 </EXAMPLE></pre> |
|
|
|
|
|
<p>Line 3 declares the xml entity. Line 6 uses the xml entity, by prefixing |
|
|
its name with '&' and following it by ';' without any spaces added. There |
|
|
are 5 predefined entities in libxml2 allowing you to escape characters with |
|
|
predefined meaning in some parts of the xml document content: |
|
|
<strong>&lt;</strong> for the character '<', <strong>&gt;</strong> |
|
|
for the character '>', <strong>&apos;</strong> for the character ''', |
|
|
<strong>&quot;</strong> for the character '"', and |
|
|
<strong>&amp;</strong> for the character '&'.</p> |
|
|
|
|
|
<p>One of the problems related to entities is that you may want the parser to |
|
|
substitute an entity's content so that you can see the replacement text in |
|
|
your application. Or you may prefer to keep entity references as such in the |
|
|
content to be able to save the document back without losing this usually |
|
|
precious information (if the user went through the pain of explicitly |
|
|
defining entities, he may have a a rather negative attitude if you blindly |
|
|
substitute them as saving time). The <a |
|
|
href="html/libxml-parser.html#xmlSubstituteEntitiesDefault">xmlSubstituteEntitiesDefault()</a> |
|
|
function allows you to check and change the behaviour, which is to not |
|
|
substitute entities by default.</p> |
|
|
|
|
|
<p>Here is the DOM tree built by libxml2 for the previous document in the |
|
|
default case:</p> |
|
|
<pre>/gnome/src/gnome-xml -> ./xmllint --debug test/ent1 |
|
|
DOCUMENT |
|
|
version=1.0 |
|
|
ELEMENT EXAMPLE |
|
|
TEXT |
|
|
content= |
|
|
ENTITY_REF |
|
|
INTERNAL_GENERAL_ENTITY xml |
|
|
content=Extensible Markup Language |
|
|
TEXT |
|
|
content=</pre> |
|
|
|
|
|
<p>And here is the result when substituting entities:</p> |
|
|
<pre>/gnome/src/gnome-xml -> ./tester --debug --noent test/ent1 |
|
|
DOCUMENT |
|
|
version=1.0 |
|
|
ELEMENT EXAMPLE |
|
|
TEXT |
|
|
content= Extensible Markup Language</pre> |
|
|
|
|
|
<p>So, entities or no entities? Basically, it depends on your use case. I |
|
|
suggest that you keep the non-substituting default behaviour and avoid using |
|
|
entities in your XML document or data if you are not willing to handle the |
|
|
entity references elements in the DOM tree.</p> |
|
|
|
|
|
<p>Note that at save time libxml2 enforces the conversion of the predefined |
|
|
entities where necessary to prevent well-formedness problems, and will also |
|
|
transparently replace those with chars (i.e. it will not generate entity |
|
|
reference elements in the DOM tree or call the reference() SAX callback when |
|
|
finding them in the input).</p> |
|
|
|
|
|
<p><span style="background-color: #FF0000">WARNING</span>: handling entities |
|
|
on top of the libxml2 SAX interface is difficult!!! If you plan to use |
|
|
non-predefined entities in your documents, then the learning curve to handle |
|
|
then using the SAX API may be long. If you plan to use complex documents, I |
|
|
strongly suggest you consider using the DOM interface instead and let libxml |
|
|
deal with the complexity rather than trying to do it yourself.</p> |
|
|
|
|
|
<h2><a name="Namespaces">Namespaces</a></h2> |
|
|
|
|
|
<p>The libxml2 library implements <a |
|
|
href="http://www.w3.org/TR/REC-xml-names/">XML namespaces</a> support by |
|
|
recognizing namespace constructs in the input, and does namespace lookup |
|
|
automatically when building the DOM tree. A namespace declaration is |
|
|
associated with an in-memory structure and all elements or attributes within |
|
|
that namespace point to it. Hence testing the namespace is a simple and fast |
|
|
equality operation at the user level.</p> |
|
|
|
|
|
<p>I suggest that people using libxml2 use a namespace, and declare it in the |
|
|
root element of their document as the default namespace. Then they don't need |
|
|
to use the prefix in the content but we will have a basis for future semantic |
|
|
refinement and merging of data from different sources. This doesn't increase |
|
|
the size of the XML output significantly, but significantly increases its |
|
|
value in the long-term. Example:</p> |
|
|
<pre><mydoc xmlns="http://mydoc.example.org/schemas/"> |
|
|
<elem1>...</elem1> |
|
|
<elem2>...</elem2> |
|
|
</mydoc></pre> |
|
|
|
|
|
<p>The namespace value has to be an absolute URL, but the URL doesn't have to |
|
|
point to any existing resource on the Web. It will bind all the element and |
|
|
attributes with that URL. I suggest to use an URL within a domain you |
|
|
control, and that the URL should contain some kind of version information if |
|
|
possible. For example, <code>"http://www.gnome.org/gnumeric/1.0/"</code> is a |
|
|
good namespace scheme.</p> |
|
|
|
|
|
<p>Then when you load a file, make sure that a namespace carrying the |
|
|
version-independent prefix is installed on the root element of your document, |
|
|
and if the version information don't match something you know, warn the user |
|
|
and be liberal in what you accept as the input. Also do *not* try to base |
|
|
namespace checking on the prefix value. <foo:text> may be exactly the |
|
|
same as <bar:text> in another document. What really matters is the URI |
|
|
associated with the element or the attribute, not the prefix string (which is |
|
|
just a shortcut for the full URI). In libxml, element and attributes have an |
|
|
<code>ns</code> field pointing to an xmlNs structure detailing the namespace |
|
|
prefix and its URI.</p> |
|
|
|
|
|
<p>@@Interfaces@@</p> |
|
|
<pre>xmlNodePtr node; |
|
|
if(!strncmp(node->name,"mytag",5) |
|
|
&& node->ns |
|
|
&& !strcmp(node->ns->href,"http://www.mysite.com/myns/1.0")) { |
|
|
... |
|
|
}</pre> |
|
|
|
|
|
<p>Usually people object to using namespaces together with validity checking. |
|
|
I will try to make sure that using namespaces won't break validity checking, |
|
|
so even if you plan to use or currently are using validation I strongly |
|
|
suggest adding namespaces to your document. A default namespace scheme |
|
|
<code>xmlns="http://...."</code> should not break validity even on less |
|
|
flexible parsers. Using namespaces to mix and differentiate content coming |
|
|
from multiple DTDs will certainly break current validation schemes. To check |
|
|
such documents one needs to use schema-validation, which is supported in |
|
|
libxml2 as well. See <a href="http://www.relaxng.org/">relagx-ng</a> and <a |
|
|
href="http://www.w3c.org/XML/Schema">w3c-schema</a>.</p> |

<h2><a name="Upgrading">Upgrading 1.x code</a></h2> |
|
|
|
|
|
<p>Incompatible changes:</p> |
|
|
|
|
|
<p>Version 2 of libxml2 is the first version introducing serious backward |
|
|
incompatible changes. The main goals were:</p> |
|
|
<ul> |
|
|
<li>a general cleanup. A number of mistakes inherited from the very early |
|
|
versions couldn't be changed due to compatibility constraints. Example |
|
|
the "childs" element in the nodes.</li> |
|
|
<li>Uniformization of the various nodes, at least for their header and link |
|
|
parts (doc, parent, children, prev, next), the goal is a simpler |
|
|
programming model and simplifying the task of the DOM implementors.</li> |
|
|
<li>better conformances to the XML specification, for example version 1.x |
|
|
had an heuristic to try to detect ignorable white spaces. As a result the |
|
|
SAX event generated were ignorableWhitespace() while the spec requires |
|
|
character() in that case. This also mean that a number of DOM node |
|
|
containing blank text may populate the DOM tree which were not present |
|
|
before.</li> |
|
|
</ul> |
|
|
|
|
|
<h3>How to fix libxml-1.x code:</h3> |
|
|
|
|
|
<p>So client code of libxml designed to run with version 1.x may have to be |
|
|
changed to compile against version 2.x of libxml. Here is a list of changes |
|
|
that I have collected, they may not be sufficient, so in case you find other |
|
|
change which are required, <a href="mailto:Daniel.Veillard@w3.org">drop me a |
|
|
mail</a>:</p> |
|
|
<ol> |
|
|
<li>The package name have changed from libxml to libxml2, the library name |
|
|
is now -lxml2 . There is a new xml2-config script which should be used to |
|
|
select the right parameters libxml2</li> |
|
|
<li>Node <strong>childs</strong> field has been renamed |
|
|
<strong>children</strong> so s/childs/children/g should be applied |
|
|
(probability of having "childs" anywhere else is close to 0+</li> |
|
|
<li>The document don't have anymore a <strong>root</strong> element it has |
|
|
been replaced by <strong>children</strong> and usually you will get a |
|
|
list of element here. For example a Dtd element for the internal subset |
|
|
and it's declaration may be found in that list, as well as processing |
|
|
instructions or comments found before or after the document root element. |
|
|
Use <strong>xmlDocGetRootElement(doc)</strong> to get the root element of |
|
|
a document. Alternatively if you are sure to not reference DTDs nor have |
|
|
PIs or comments before or after the root element |
|
|
s/->root/->children/g will probably do it.</li> |
|
|
<li>The white space issue, this one is more complex, unless special case of |
|
|
validating parsing, the line breaks and spaces usually used for indenting |
|
|
and formatting the document content becomes significant. So they are |
|
|
reported by SAX and if your using the DOM tree, corresponding nodes are |
|
|
generated. Too approach can be taken: |
|
|
<ol> |
|
|
<li>lazy one, use the compatibility call |
|
|
<strong>xmlKeepBlanksDefault(0)</strong> but be aware that you are |
|
|
relying on a special (and possibly broken) set of heuristics of |
|
|
libxml to detect ignorable blanks. Don't complain if it breaks or |
|
|
make your application not 100% clean w.r.t. to it's input.</li> |
|
|
<li>the Right Way: change you code to accept possibly insignificant |
|
|
blanks characters, or have your tree populated with weird blank text |
|
|
nodes. You can spot them using the commodity function |
|
|
<strong>xmlIsBlankNode(node)</strong> returning 1 for such blank |
|
|
nodes.</li> |
|
|
</ol> |
|
|
<p>Note also that with the new default the output functions don't add any |
|
|
extra indentation when saving a tree in order to be able to round trip |
|
|
(read and save) without inflating the document with extra formatting |
|
|
chars.</p> |
|
|
</li> |
|
|
<li>The include path has changed to $prefix/libxml/ and the includes |
|
|
themselves uses this new prefix in includes instructions... If you are |
|
|
using (as expected) the |
|
|
<pre>xml2-config --cflags</pre> |
|
|
<p>output to generate you compile commands this will probably work out of |
|
|
the box</p> |
|
|
</li> |
|
|
<li>xmlDetectCharEncoding takes an extra argument indicating the length in |
|
|
byte of the head of the document available for character detection.</li> |
|
|
</ol> |
|
|
|
|
|
<h3>Ensuring both libxml-1.x and libxml-2.x compatibility</h3> |
|
|
|
|
|
<p>Two new version of libxml (1.8.11) and libxml2 (2.3.4) have been released |
|
|
to allow smooth upgrade of existing libxml v1code while retaining |
|
|
compatibility. They offers the following:</p> |
|
|
<ol> |
|
|
<li>similar include naming, one should use |
|
|
<strong>#include<libxml/...></strong> in both cases.</li> |
|
|
<li>similar identifiers defined via macros for the child and root fields: |
|
|
respectively <strong>xmlChildrenNode</strong> and |
|
|
<strong>xmlRootNode</strong></li> |
|
|
<li>a new macro <strong>LIBXML_TEST_VERSION</strong> which should be |
|
|
inserted once in the client code</li> |

|
|
|
|
|
<p>So the roadmap to upgrade your existing libxml applications is the |
|
|
following:</p> |
|
|
<ol> |
|
|
<li>install the libxml-1.8.8 (and libxml-devel-1.8.8) packages</li> |
|
|
<li>find all occurrences where the xmlDoc <strong>root</strong> field is |
|
|
used and change it to <strong>xmlRootNode</strong></li> |
|
|
<li>similarly find all occurrences where the xmlNode |
|
|
<strong>childs</strong> field is used and change it to |
|
|
<strong>xmlChildrenNode</strong></li> |
|
|
<li>add a <strong>LIBXML_TEST_VERSION</strong> macro somewhere in your |
|
|
<strong>main()</strong> or in the library init entry point</li> |
|
|
<li>Recompile, check compatibility, it should still work</li> |
|
|
<li>Change your configure script to look first for xml2-config and fall |
|
|
back using xml-config . Use the --cflags and --libs output of the command |
|
|
as the Include and Linking parameters needed to use libxml.</li> |
|
|
<li>install libxml2-2.3.x and libxml2-devel-2.3.x (libxml-1.8.y and |
|
|
libxml-devel-1.8.y can be kept simultaneously)</li> |
|
|
<li>remove your config.cache, relaunch your configuration mechanism, and |
|
|
recompile, if steps 2 and 3 were done right it should compile as-is</li> |
|
|
<li>Test that your application is still running correctly, if not this may |
|
|
be due to extra empty nodes due to formating spaces being kept in libxml2 |
|
|
contrary to libxml1, in that case insert xmlKeepBlanksDefault(1) in your |
|
|
code before calling the parser (next to |
|
|
<strong>LIBXML_TEST_VERSION</strong> is a fine place).</li> |
|
|
</ol> |
|
|
|
|
|
<p>Following those steps should work. It worked for some of my own code.</p> |
|
|
|
|
|
<p>Let me put some emphasis on the fact that there is far more changes from |
|
|
libxml 1.x to 2.x than the ones you may have to patch for. The overall code |
|
|
has been considerably cleaned up and the conformance to the XML specification |
|
|
has been drastically improved too. Don't take those changes as an excuse to |
|
|
not upgrade, it may cost a lot on the long term ...</p> |

<h2><a name="Thread">Thread safety</a></h2> |
|
|
|
|
|
<p>Starting with 2.4.7, libxml2 makes provisions to ensure that concurrent |
|
|
threads can safely work in parallel parsing different documents. There is |
|
|
however a couple of things to do to ensure it:</p> |
|
|
<ul> |
|
|
<li>configure the library accordingly using the --with-threads options</li> |
|
|
<li>call xmlInitParser() in the "main" thread before using any of the |
|
|
libxml2 API (except possibly selecting a different memory allocator)</li> |
|
|
</ul> |
|
|
|
|
|
<p>Note that the thread safety cannot be ensured for multiple threads sharing |
|
|
the same document, the locking must be done at the application level, libxml |
|
|
exports a basic mutex and reentrant mutexes API in <libxml/threads.h>. |
|
|
The parts of the library checked for thread safety are:</p> |
|
|
<ul> |
|
|
<li>concurrent loading</li> |
|
|
<li>file access resolution</li> |
|
|
<li>catalog access</li> |
|
|
<li>catalog building</li> |
|
|
<li>entities lookup/accesses</li> |
|
|
<li>validation</li> |
|
|
<li>global variables per-thread override</li> |
|
|
<li>memory handling</li> |
|
|
</ul> |
|
|
|
|
|
<p>XPath has been tested for threaded usage on non-modified document |
|
|
for example when using libxslt, but make 100% sure the documents |
|
|
are accessed read-only !</p> |
|
|
|
|
|
<h2><a name="DOM"></a><a name="Principles">DOM Principles</a></h2> |
|
|
|
|
|
<p><a href="http://www.w3.org/DOM/">DOM</a> stands for the <em>Document |
|
|
Object Model</em>; this is an API for accessing XML or HTML structured |
|
|
documents. Native support for DOM in Gnome is on the way (module gnome-dom), |
|
|
and will be based on gnome-xml. This will be a far cleaner interface to |
|
|
manipulate XML files within Gnome since it won't expose the internal |
|
|
structure.</p> |
|
|
|
|
|
<p>The current DOM implementation on top of libxml2 is the <a |
|
|
href="http://svn.gnome.org/viewvc/gdome2/trunk/">gdome2 Gnome module</a>, this |
|
|
is a full DOM interface, thanks to Paolo Casarini, check the <a |
|
|
href="http://gdome2.cs.unibo.it/">Gdome2 homepage</a> for more |
|
|
information.</p> |

<h2><a name="Example"></a><a name="real">A real example</a></h2> |
|
|
|
|
|
<p>Here is a real size example, where the actual content of the application |
|
|
data is not kept in the DOM tree but uses internal structures. It is based on |
|
|
a proposal to keep a database of jobs related to Gnome, with an XML based |
|
|
storage structure. Here is an <a href="gjobs.xml">XML encoded jobs |

compressed and uncompressed files and/or file systems to be backed |
|
|
up with a supported media in the system. This should be able to |
|

to tar, dd, cpio, cp, gzip, etc., to be directed to the tape machine |
|

|
<p>While loading the XML file into an internal DOM tree is a matter of |
|
|
calling only a couple of functions, browsing the tree to gather the data and |
|
|
generate the internal structures is harder, and more error prone.</p> |
|
|
|
|
|
<p>The suggested principle is to be tolerant with respect to the input |
|
|
structure. For example, the ordering of the attributes is not significant, |
|
|
the XML specification is clear about it. It's also usually a good idea not to |
|
|
depend on the order of the children of a given node, unless it really makes |
|
|
things harder. Here is some code to parse the information for a person:</p> |
|
|
<pre>/* |
|
|
* A person record |
|
|
*/ |
|
|
typedef struct person { |
|
|
char *name; |
|
|
char *email; |
|
|
char *company; |
|
|
char *organisation; |
|
|
char *smail; |
|
|
char *webPage; |
|
|
char *phone; |
|
|
} person, *personPtr; |
|
|
|
|
|
/* |
|
|
* And the code needed to parse it |
|
|
*/ |
|
|
personPtr parsePerson(xmlDocPtr doc, xmlNsPtr ns, xmlNodePtr cur) { |
|
|
personPtr ret = NULL; |
|
|
|
|
|
DEBUG("parsePerson\n"); |
|
|
/* |
|
|
* allocate the struct |
|
|
*/ |
|
|
ret = (personPtr) malloc(sizeof(person)); |
|
|
if (ret == NULL) { |
|
|
fprintf(stderr,"out of memory\n"); |
|
|
return(NULL); |
|
|
} |
|
|
memset(ret, 0, sizeof(person)); |
|
|
|
|
|
/* We don't care what the top level element name is */ |
|
|
cur = cur->xmlChildrenNode; |
|
|
while (cur != NULL) { |
|
|
if ((!strcmp(cur->name, "Person")) && (cur->ns == ns)) |
|
|
ret->name = xmlNodeListGetString(doc, cur->xmlChildrenNode, 1); |
|
|
if ((!strcmp(cur->name, "Email")) && (cur->ns == ns)) |
|
|
ret->email = xmlNodeListGetString(doc, cur->xmlChildrenNode, 1); |
|
|
cur = cur->next; |
|
|
} |
|
|
|
|
|
return(ret); |
|
|
}</pre> |
|
|
|
|
|
<p>Here are a couple of things to notice:</p> |
|
|
<ul> |
|
|
<li>Usually a recursive parsing style is the more convenient one: XML data |
|
|
is by nature subject to repetitive constructs and usually exhibits highly |
|
|
structured patterns.</li> |
|
|
<li>The two arguments of type <em>xmlDocPtr</em> and <em>xmlNsPtr</em>, |
|
|
i.e. the pointer to the global XML document and the namespace reserved to |
|
|
the application. Document wide information are needed for example to |
|
|
decode entities and it's a good coding practice to define a namespace for |
|
|
your application set of data and test that the element and attributes |
|
|
you're analyzing actually pertains to your application space. This is |
|
|
done by a simple equality test (cur->ns == ns).</li> |
|
|
<li>To retrieve text and attributes value, you can use the function |
|
|
<em>xmlNodeListGetString</em> to gather all the text and entity reference |
|
|
nodes generated by the DOM output and produce an single text string.</li> |
|
|
</ul> |
|
|
|
|
|
<p>Here is another piece of code used to parse another level of the |
|
|
structure:</p> |
|
|
<pre>#include <libxml/tree.h> |
|
|
/* |
|
|
* a Description for a Job |
|
|
*/ |
|
|
typedef struct job { |
|
|
char *projectID; |
|
|
char *application; |
|
|
char *category; |
|
|
personPtr contact; |
|
|
int nbDevelopers; |
|
|
personPtr developers[100]; /* using dynamic alloc is left as an exercise */ |
|
|
} job, *jobPtr; |
|
|
|
|
|
/* |
|
|
* And the code needed to parse it |
|
|
*/ |
|
|
jobPtr parseJob(xmlDocPtr doc, xmlNsPtr ns, xmlNodePtr cur) { |
|
|
jobPtr ret = NULL; |
|
|
|
|
|
DEBUG("parseJob\n"); |
|
|
/* |
|
|
* allocate the struct |
|
|
*/ |
|
|
ret = (jobPtr) malloc(sizeof(job)); |
|
|
if (ret == NULL) { |
|
|
fprintf(stderr,"out of memory\n"); |
|
|
return(NULL); |
|
|
} |
|
|
memset(ret, 0, sizeof(job)); |
|
|
|
|
|
/* We don't care what the top level element name is */ |
|
|
cur = cur->xmlChildrenNode; |
|
|
while (cur != NULL) { |
|
|
|
|
|
if ((!strcmp(cur->name, "Project")) && (cur->ns == ns)) { |
|
|
ret->projectID = xmlGetProp(cur, "ID"); |
|
|
if (ret->projectID == NULL) { |
|
|
fprintf(stderr, "Project has no ID\n"); |
|
|
} |
|
|
} |
|
|
if ((!strcmp(cur->name, "Application")) && (cur->ns == ns)) |
|
|
ret->application = xmlNodeListGetString(doc, cur->xmlChildrenNode, 1); |
|
|
if ((!strcmp(cur->name, "Category")) && (cur->ns == ns)) |
|
|
ret->category = xmlNodeListGetString(doc, cur->xmlChildrenNode, 1); |
|
|
if ((!strcmp(cur->name, "Contact")) && (cur->ns == ns)) |
|
|
ret->contact = parsePerson(doc, ns, cur); |
|
|
cur = cur->next; |
|
|
} |
|
|
|
|
|
return(ret); |
|
|
}</pre> |
|
|
|
|
|
<p>Once you are used to it, writing this kind of code is quite simple, but |
|
|
boring. Ultimately, it could be possible to write stubbers taking either C |
|
|
data structure definitions, a set of XML examples or an XML DTD and produce |
|
|
the code needed to import and export the content between C data and XML |
|
|
storage. This is left as an exercise to the reader :-)</p> |
|
|
|
|
|
<p>Feel free to use <a href="example/gjobread.c">the code for the full C |
|
|
parsing example</a> as a template, it is also available with Makefile in the |
|
|
Gnome SVN base under libxml2/example</p> |
