# 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

<h1>[% item.getAttribute('title') | html %]</h1>
[% item.content(view) %]

renders

[% BLOCK xmlstring;
item.starttag; item.content(view); item.endtag;
END %]
# block to generate simple text
[% BLOCK text; item | html; END %]

[% repview.print(page) %]
# or print node content via view
[% page.content(repview) %]
PRE-REQUISITES
- 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
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.end
- tag %]
- To render out the start tag, followed by the content ren
dered in the view "view", followed by the end tag.
