Libxml-Ruby

The Libxml-Ruby project provides Ruby language bindings for the GNOME Libxml2 XML toolkit. Libxml-ruby's primary advantage over REXML is performance - if speed is your need, this is the good libraries to consider. Libxml-Ruby supports installation via both the standard Ruby extconf install and "Rubygems": http://rubygems.rubyforge.org/. In either case the requirements are the same - only the installation process differs.
