    <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="http://xmlsoft.org/python.html">a variety of language bindings</a> make it available in
other environments.</p>
    <p>Libxml2 implements a number of existing standards related to markup
languages:</p>
