Yesterday I added basic RSS1 support to XML_Feed_Parser and began the process of preparing a PEPR proposal to have it included in PEAR. I still need to get the various pages about the module in sync, but the code and a rough to-do list are currently available on my test server.
My key desire is to add in support for RSS1 modules and RSS2 namespaces so that I can begin to use it to get at richer content than the base RSS1-spec allows. I’ll probably add some mappings for some of the more common extensions and then define a way for users to interact with those that are less common. If anyone has any preferred ways of doing that, feel free to suggest them in the comments.
