Generating RSS from XHTML page?

Did anybody do such things? Attached is my first attempt which is obviously 
not succesful. (I am not interested in DB-only solution like website DTD, 
just to generate RSS -- or Atom, it doesn't matter -- from a page or set 
of pages in one directory).

	Thanks for any hints,
