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

an HTML fragment.
- imageAlign
- A string, has two possible values, left or right. The channel image is
either left-aligned or right-aligned. It defaults to right aligned.

if not present.
- textinput
- Get the textinput of a channel as an RDF::Redland::RSS::Node object or
undef if not present.
- property
PROPERTY
