Someone Geoffrey Sneddon (one of the SimplePie devs) left me a comment complaining about my quick and dirty feed merger script in PHP. It hadn't considered it before, but my CData fields could break. I was thinking, "I should do this the right way..." and since I use the DOM a lot in my transcoding stuff, I'm familiar with the methods. I mean, it's not hard, it's just very, very verbose.

Attached below.
