libxml2 is a software library for parsing XML documents. It is also the basis for the libxslt library which processes XSLT-1.0 stylesheets.
Written in the C programming language, libxml2 provides bindings to C++, Ch, XSH, C#, Python, Kylix/Delphi and other Pascals, Ruby, Common Lisp, and PHP.  It can be accessed from the Perl programming language using the XML::LibXML module. It was originally developed for the GNOME project, but can be used outside it. The libXML code is highly portable, since it depends on standard ANSI C libraries only,  and it is released under the MIT license. This library was written by Daniel Veillard and enjoys active feedback from its users.
It includes the command-line utility xmllint and an HTML parser.
