Geeklog Forums

Hey,
I was just wondering how i would be able to make a new php block that parses xml files differently.
Currently, the default geeklog rdf thing grabs the 'link' and 'title' information from the rdf file. I want to instead grab the 'content' and 'description' parts and display these in a block. I figure this would be easy and would involve just rewriting the code with 2 simple changes--but i'm lackin in php knowledge and would appreciate some help.

Thanks
