NAME
       Template::Plugin::XML::XPath - Plugin interface to XML::XPath

SYNOPSIS
           # load plugin and specify XML file to parse
           [% USE xpath = XML.XPath(xmlfile) %]
           [% USE xpath = XML.XPath(file => xmlfile) %]
           [% USE xpath = XML.XPath(filename => xmlfile) %]

           # load plugin and specify XML text to parse
           [% USE xpath = XML.XPath(xmltext) %]
           [% USE xpath = XML.XPath(xml => xmltext) %]
           [% USE xpath = XML.XPath(text => xmltext) %]

           # then call any XPath methods (see XML::XPath docs)
           [% FOREACH page = xpath.findnodes('/html/body/page') %]
              [% page.getAttribute('title') %]
           [% END %]

           # define VIEW to present node(s)
           [% VIEW repview notfound='xmlstring' %]
              # handler block for a <report>...</report> element
              [% BLOCK report %]
                 [% item.content(view) %]
              [% END %]

              # handler block for a <section title="...">...</section> element
              [% BLOCK section %]
              <h1>[% item.getAttribute('title') | html %]</h1>
              [% item.content(view) %]
              [% END %]

              # default template block passes tags through and renders
              # out the children recursivly
              [% BLOCK xmlstring;
                 item.starttag; item.content(view); item.endtag;
              END %]

              # block to generate simple text
              [% BLOCK text; item | html; END %]
           [% END %]

           # now present node (and children) via view
           [% repview.print(page) %]

           # or print node content via view
           [% page.content(repview) %]

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.

       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.
