Easy way is just look at an rss feed's xml and apply it to yours
But I think it's much easier to apply rss then how you do php news because rss takes over and everytime u do a new item it goes to the front page or where ever.
Once you decide please put it on igator, my yahoo, google, all the other rss readers out there so it lets people use their own instead of bookmarking and reading it that way. Rss is old now i forgot about it. I'm now using podcasts on itunes and other ways to get news
