Hmm..this all makes perfect sense while reading the code, and yet I
still get the same error. I'm guessing that preg_match('/<\?xml/',
$data) found the string, and the preg_replace() was to remove
everything before it?

I think the problem is, it never actually removed the header text.
When I hit the xml_parse, it stills parses ALL of $data. (otherwise I
wouldn't get the error).

I tried to test this theory by commenting out the preg_replace, but
nothing changed and viewing the data with view source looks the
same... note I did change my fopen() parameter to 'r+' so it is open
to read and write (and the permissions are set to 777).

I definitely appreciate the help so far, I'm surprised this didn't
work! Any other directions to point me in? (or anyone else?)
