I prefer amara:

>>> from amara import bindery
>>> doc =3D bindery.parse("http://maps.google.com/maps/api/geocode/xml?addr=
ess=3D50+Oakland+St,Wellesley,MA,02481&sensor=3Dtrue")
>>> locations =3D doc.xml_select(u'//location')
>>> for loc in locations:
...     print loc.lat, loc.lng
...
42.3118520 -71.2632680
