Try running it interactively and looking at the data you receive:

>>> conn = HTTPConnection('xml.showmyip.com')
>>> conn.request('GET', '/')

>>> resp = conn.getresponse()
>>> print resp
<httplib.HTTPResponse instance at 0x00C58350>
>>> data = resp.read()
>>> print data
<html><head><title>Object moved</title></head><body>

<h2>Object moved to <a href="http://www.showmyip.com/xml/">here</a>.
</h2>

</body></html>

If you try connecting to 'www.showmyip.com' and requesting '/xml/' it 
should work.
