<h1 align="center">The XSLT C library for GNOME</h1>
<h1 style="text-align: center">libxslt</h1>
<p>Libxslt is the <a href="http://www.w3.org/TR/xslt">XSLT</a> C library
developed for the GNOME project. XSLT itself is a an XML language to define
transformation for XML. Libxslt is based on <a
href="http://xmlsoft.org/">libxml2</a> the XML C library developed for the
GNOME project. It also implements most of the <a
href="http://www.exslt.org/">EXSLT</a> set of processor-portable extensions
functions and some of Saxon's evaluate and expressions extensions.</p>
<p>People can either embed the library in their application or use xsltproc
the command line processing tool. This library is free software and can be
reused in commercial applications (see the <a href="intro.html">intro</a>)</p>
<p>External documents:</p>
<ul>
<li>John Fleck wrote <a href="tutorial/libxslttutorial.html">a tutorial for
libxslt</a></li>
<li><a href="xsltproc.html">xsltproc user manual</a></li>
<li><a href="http://xmlsoft.org/">the libxml documentation</a></li>

<h2><a name="Introducti">Introduction</a></h2>
<p>This document describes <a href="http://xmlsoft.org/XSLT/">libxslt</a>,
the <a href="http://www.w3.org/TR/xslt">XSLT</a> C library developed for the
<a href="http://www.gnome.org/">GNOME</a> project.</p>
<p>Here are some key points about libxslt:</p>
<ul>
<li>Libxslt is a C implementation</li>
<li>Libxslt is based on libxml for XML parsing, tree manipulation and XPath
support</li>
<li>It is written in plain C, making as few assumptions as possible, and
sticking closely to ANSI C/POSIX for easy embedding. Should works on
Linux/Unix/Windows.</li>
<li>This library is released under the <a
href="http://www.opensource.org/licenses/mit-license.html">MIT
Licence</a></li>
<li>Though not designed primarily with performances in mind, libxslt seems
to be a relatively fast processor.</li>
</ul>
<h2><a name="Documentat">Documentation</a></h2>
<p>There are some on-line resources about using libxslt:</p>
<ol>
<li>Check the <a href="html/libxslt-lib.html#LIBXSLT-LIB">API
documentation</a> automatically extracted from code comments (using the
program apibuild.py, developed for libxml, together with the xsl script
'newapi.xsl' and the libxslt xsltproc program).</li>
<li>Look at the <a href="http://mail.gnome.org/archives/xslt/">mailing-list
archive</a>.</li>
<li>Of course since libxslt is based on libxml, it's a good idea to at
least read <a href="http://xmlsoft.org/">libxml description</a></li>
</ol>
<h2><a name="Reporting">Reporting bugs and getting help</a></h2>
<p>If you need help with the XSLT language itself, here are a number of
useful resources:</p>
<ul>
<li>I strongly suggest to subscribe to <a
href="http://www.mulberrytech.com/xsl/xsl-list">XSL-list</a>, check <a
href="http://www.biglist.com/lists/xsl-list/archives/">the XSL-list
archives</a></li>
<li>The <a href="http://www.dpawson.co.uk/xsl/xslfaq.html">XSL FAQ</a>.</li>
<li>The <a
href="http://www.nwalsh.com/docs/tutorials/xsl/xsl/slides.html">tutorial</a>
written by Paul Grosso and Norman Walsh is a very good on-line
introdution to the language.</li>
<li>The <a
href="http://www.zvon.org/xxl/XSLTutorial/Books/Book1/index.html">only
Zvon XSLT tutorial</a> details a lot of constructs with examples.</li>
<li><a href="http://www.jenitennison.com/xslt/index.html">Jeni Tennison's
XSLT</a> pages provide links to a lot of answers</li>
<li>the <a href="http://incrementaldevelopment.com/xsltrick/">Gallery of
XSLT Tricks</a> provides non-standard use case of XSLT</li>
<li>And I suggest to buy Michael Kay "XSLT Programmer's Reference" book
published by <a href="http://www.wrox.com/">Wrox</a> if you plan to work
seriously with XSLT in the future.</li>
</ul>
<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/enter_bug.cgi?product=libxslt">GNOME bug
tracking database</a> (make sure to use the "libxslt" module name). Before
filing a bug, check the <a
href="http://bugzilla.gnome.org/buglist.cgi?product=libxslt">list of existing
libxslt bugs</a> to make sure it hasn't already been filed. 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 libxslt.</p>
<p>For small problems you can try to get help on IRC, the #xml channel on
irc.gnome.org (port 6667) usually have a few person 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:xslt@gnome.org">xslt@gnome.org</a> for libxslt, with an <a
href="http://mail.gnome.org/archives/xslt/">on-line archive</a>. To subscribe
to this list, please visit the <a
href="http://mail.gnome.org/mailman/listinfo/xslt">associated Web</a> page
and follow the instructions.</p>
<p>Alternatively, you can just send the bug to the <a
href="mailto:xslt@gnome.org">xslt@gnome.org</a> list, if it's really libxslt
related I will approve it.. Please do not send me mail directly especially
for portability problem, it makes things really harder to track and in some
cases I'm not the best person to answer a given question, ask the list
instead. <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

posting</span>:</p>
<ul>
<li><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/libxslt/">using a recent
version</a>, and that the problem still shows up in those</li>
<li>check the <a href="http://mail.gnome.org/archives/xslt/">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=libxslt">registered
open bugs</a></li>
<li>make sure you can reproduce the bug with xsltproc, a very useful thing
to do is run the transformation with -v argument and redirect the
standard error to a file, then search in this file for the transformation
logs just preceding the possible problem</li>
<li>Please send the command showing the error as well as the input and
stylesheet (as an attachment)</li>
</ul>
<p>Then send the bug with associated information to reproduce it to the <a
href="mailto:xslt@gnome.org">xslt@gnome.org</a> list; if it's really libxslt
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">request 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
xslt@gnome.org mailing list for any technical reply made about libxml2 or
libxslt.</li>
<li>There is <span style="color: #E50000">no guarantee for 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 reports with a suggested patch for fixing them will
probably be processed faster.</p>
<p>If you're looking for help, a quick look at <a
href="http://mail.gnome.org/archives/xslt/">the list archive</a> may actually
provide the answer, I usually send source samples when answering libxslt
usage questions. The <a
href="html/libxslt-lib.html#LIBXSLT-LIB">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>

<h2><a name="FAQ">FAQ</a></h2>
<ol>
<li><em>Troubles compiling or linking programs using libxslt</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>xslt-config</code> which is installed as part of libxslt usual
install process which provides those flags. Use</p>
<p><code>xslt-config --cflags</code></p>
<p>to get the compilation flags and</p>
<p><code>xslt-config --libs</code></p>
<p>to get the linker flags. Usually this is done directly from the
Makefile as:</p>
<p><code>CFLAGS=`xslt-config --cflags`</code></p>
<p><code>LIBS=`xslt-config --libs`</code></p>
<p>Note also that if you use the EXSLT extensions from the program then
you should prepend <code>-lexslt</code> to the LIBS options</p>
</li>
<li><em>passing parameters on the xsltproc command line doesn't work</em>
<p><em>xsltproc --param test alpha foo.xsl foo.xml</em></p>
<p><em>the param does not get passed and ends up as ""</em></p>
<p>In a nutshell do a double escaping at the shell prompt:</p>
<p>xsltproc --param test "'alpha'" foo.xsl foo.xml</p>
<p>i.e. the string value is surrounded by " and ' then terminated by '
and ". Libxslt interpret the parameter values as XPath expressions, so
the string -><code>alpha</code><- is intepreted as the node set
matching this string. You really want -><code>'alpha'</code><- to
be passed to the processor. And to allow this you need to escape the
quotes at the shell level using -><code>"'alpha'"</code><- .</p>
<p>or use</p>
<p>xsltproc --stringparam test alpha foo.xsl foo.xml</p>
</li>
<li><em>Is there C++ bindings ?</em>
<p>Yes for example <a
href="http://pmade.org/pjones/software/xmlwrapp/">xmlwrapp</a> , see <a
href="python.html">the related pages about bindings</a></p>
