NAME

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.
