Simple XML/RSS Reader APP

[PurpleTreePanda]

I'm making an app for my high school and the school wants an RSS Feed Reader to be part of the APP.
I've been trying to implement the XML parser into the app for a few weeks now, but no matter what tutorial i read/watch i cant seem to make it work.
Im using iOS 5 Beta 7, and sdk 4.2 Beta 7
