Horde_Feed_Rss extends Horde_Feed_Base

RSS channel class

The Horde_Feed_Rss class is a concrete subclass of Horde_Feed_Base meant for representing RSS channels. It does not add any methods to its parent, just provides a classname to check against with the instanceof operator, and expects to be handling RSS-formatted data instead of Atom.
