DESCRIPTION

       A class for processing RSS 1.0 as RDF, traversing the resulting graph using RSS
       propertiiies and formatting the output as XHTML.

CONSTRUCTORS

       new SOURCE_URI_STRING [BASE_URI_STRING]
           Process RSS 1.0 at source URI SOURCE_URI_STRING. If the BASE_URI_STRING string is
           given then use that as the base URI rather than the source URI.

       new MODEL
           Process RSS 1.0 from content stored in RDF::Redland::Model MODEL.

METHODS

       channels
           Return the RSS channels (<channel> tags) as a list of RDF::Redland::RSS::Node objects.

       items
           Return the RSS items (<item> tags) as a list of RDF::Redland::RSS::Node objects.

       image
           Return the RSS 1.0 image (<image> tag) as an RDF::Redland::RSS::Node object.

       textinput
           Return the RSS 1.0 textinput (<textinput> tag) as an RDF::Redland::RSS::Node object.

       as_xhtml (key1 => value1, key2 => value2, ...)
           Return a formatted XHTML string (or full XHTML document) representing the RSS 1.0
           content with various options set as listed in the section below.

           The parameters to this method are mostly from the specification of the viewRssBox
           macro at http://macros.userland.com/viewRssBox
