NAME

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

SYNOPSIS

     [% USE news = XML.RSS('news.rdf') %]
    
     [% FOREACH item IN news.items %]
        [% item.title %]
        [% item.link  %]
     [% END %]

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 IN news.items %]
        [% item.title %]
        [% item.link  %]
     [% END %]
