NAME

Template::Plugin::XML::RSS - Plugin interface to XML::RSS

SYNOPSIS

 [% USE news = XML.RSS($filename) %]

 [% FOREACH item = news.items %]
    [% item.title %]
    [% item.link  %]
 [% END %]

PRE-REQUISITES

This plugin requires that the XML::Parser and XML::RSS modules be installed. These are available from CPAN:

http://www.cpan.org/modules/by-module/XML

DESCRIPTION

This Template Toolkit plugin provides a simple interface to the XML::RSS module.

[% USE news = XML.RSS('mysite.rdf') %]

It creates an XML::RSS object, which is then used to parse the RSS file specified as a parameter in the USE directive. A reference to the XML::RSS object is then returned.

An RSS (Rich Site Summary) file is typically used to store short news 'headlines' describing different links within a site. This example is extracted from http://slashdot.org/slashdot.rdf.

The attributes of the channel and image elements can be retrieved directly from the plugin object using the familiar dotted compound notation:

[% news.channel.title  %]
[% news.channel.link   %]
[% news.channel.etc... %]  

[% news.image.title    %]
[% news.image.url      %]
[% news.image.link     %]
[% news.image.etc...   %]

The list of news items can be retrieved using the 'items' method:

[% FOREACH item = news.items %]
   [% item.title %]
   [% item.link  %]
[% END %]
