Socket XML Parser

Hi,

I need to be able to parse XML recieved from a socket. Every socket.readLine makes a complete XML (document?) (A sample is provided below).

All the XML parsers I've found so far seem to be for reading XML files with close document tags etc.

Im new to java and XML so if you could explain it simply for me, Id much appreciate it. Failing that, could you point me in the direction of a decent tutorial for beginners, all the ones i've googled have gone straight over my head :$

Thanks in advance!

Just a quick format of that:

Have a look at w3schools for a tutorial on XML. But that there is valid XML, except I would ask what ns0 is, and why ns1 is declared but not used?
