NAME
Template::XML - XML plugins for the Template Toolkit SYNOPSIS
[% USE XML; dom = XML.dom('foo.xml'); xpath = XML.xpath('bar.xml'); simple = XML.simple('baz.xml'); rss = XML.simple('news.rdf'); %] DESCRIPTION
The Template-XML distribution provides a number of Template Toolkit plugin modules for working with XML. The Template::Plugin::XML module is a front-end to the various other XML plugin modules. Through this you can access XML files and direc- tories of XML files via the Template::Plugin::XML::File and Template::Plugin::XML::Directory modules (which subclass from the Tem- plate::Plugin::File and Template::Plugin::Directory modules respectively). You can then create a Document Object Model (DOM) from an XML file (Template::Plugin::XML::DOM), examine it using XPath queries (Template::Plugin::XML::XPath), turn it into a Perl data structure (Tem- plate::Plugin::XML::Simple) or parse it as an RSS (RDF Site Summary) file. The basic XML plugins were distributed as part of the Template Toolkit until version 2.15 released in May 2006. At this time they were extracted into this separate Template-XML distribution and an alpha version of this Template::Plugin::XML front-end module was added. AUTHORS
Andy Wardley wrote the Template Toolkit plugin modules, with assistance from Simon Matthews in the case of the XML::DOM plugin. Matt Sergeant wrote the XML::XPath module. Enno Derksen and Clark Cooper wrote the XML::DOM module. Jonathan Eisenzopf wrote the XML::RSS mod- ule. Grant McLean wrote the XML::Simple module. Clark Cooper and Larry Wall wrote the XML::Parser module. James Clark wrote the expat library. COPYRIGHT
