You'll need to use an external method (or write a simple product).
Then you can use httplib or urllib2, or the python wrappers for curl
(I found curl worked in some weird firewall configurations
that httplib didn't).

But you mention XML. If the remote system is XML-RPC, you'll
want to use python's excellent xmlrpclib, which makes
rpc calls look just like local calls:

remote = xmlrpclib.ServerProxy('http://somewhere/something')
result = remote.someMethod('param1', 'param2')
