What errors do you get? As long as you use valid XML, I don't see how you could get errors saving and reopening the file.

As a side note, XML is awesome. Anybody reading this thread who doesn't know XML should learn it immediately. I'm using XML for a new project at my web site that will blow your mind (I am not modest). Hint: with XML, you can publish information from vBulletin to any other application that supports XML parsing. And yes, you can create XML in PHP: http://www.php.net/dom .
