This plugin requires that the XML::Parser and XML::XPath modules be installed. These are available from CPAN:

        http://www.cpan.org/modules/by-module/XML

[%- END %] [% WRAPPER section title='DESCRIPTION' -%]

This is a Template Toolkit plugin interfacing to the XML::XPath module.

All methods implemented by the XML::XPath modules are available. In addition, the XML::XPath::Node::Element module implements present($view) and content($view) methods method for seamless integration with Template Toolkit VIEWs. The XML::XPath::Node::Text module is also adorned with a present($view) method which presents itself via the view using the 'text' template.
