If you don’t use CDATA then you need to make sure that you don’t have any reserved xml characters in your titles or stories, such as <, > and &. One thing you can do with you php script is to escape the reserved characters before passing it along, that way you don’t need to put it in CDATA. I’m assuming that you want to use e4x commands to control the data, and if so it needs to be outside a CDATA block. CDATA prevents xml formatting.
