You cannot output <?xml version="1.0" encoding="utf-8"?> unless at the very beginning of your webpage. Perhaps Netscape and Mozilla will correct such error, but an XML-document which does not start with this invocation is incorrect XML.

This of course does not solve your problem and I'm at a loss to find a solution as I do not see from your code where this top-level XML-item comes from.
