Steve,
I have never had good luck with parsing off a socket. I find it much
easier to just read off the socket myself in to a memory area, and
then parse the memory area using xmlParseMemory
Of course, if you read off the socket yourself make sure and look for
the end tag to speed things up. And, of course, don't read past the
end tag ...
