Steve,
Did you take a look at the raw data returned by the fsockopen file pointer.
There may be some http headers that are tripping up the xml parser.

Subject: [PHP] XML Parsing through Proxy
Hi Anybody got an idea?
I am sitting behind a proxy and I want to able to parse an XML.
So I have to use fsockopen() to get through my firewall and get the page.
So far, everything goes wel, but I am not able to parse the file, because I
think it is not in XML format if I use "GET http://.... "
Does anyone has an idea how I can solve this?
My code so far (bits and pieces of anywhere :) )
Steve
