PRE-REQUISITES | [ Index ] [ Modules ] [ Top ]

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

DESCRIPTION | [ Index ] [ Modules ] [ Top ]

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.

To aid the reconstruction of XML, methods starttag and endtag are added to XML::XPath::Node::Element which return the start and end tag for that element. This means that you can easily do:

      [% item.starttag %][% item.content(view) %][% item.endtag %]

To render out the start tag, followed by the content rendered in the view "view", followed by the end tag.
