Perl interface to the libxml2 library

 XML::LibXML is a Perl interface to the GNOME libxml2 library, which provides
 interfaces for parsing and manipulating XML files. This module allows Perl
 programmers to make use of the highly capable validating XML parser and the
 high performance Document Object Model (DOM) implementation. Additionally, it
 supports using the XML Path Language (XPath) to find and extract information.
