[XML-SIG] parsing XML with minidom

[Peter Bigot]

I'd have to concur with that recommendation.  Google is uninterested in
defining schema for their APIs, so you need to process the XML manually and
hope they don't change their interface.

BTW: The lat and lon components of the location are elements, not
attributes.  For minidom, use:
    lat = item.getElementsByTagName('lat')[0]
    lat.normalize()
    print lat.firstChild.data

Much easier when you can generate a proper binding from a schema, or use
something like Amara that does so without a schema.
