use "inspect", "type" and __class__
here an example:
from xml.dom import minidom
aproxy='someps.proxy'
xmldoc = minidom.parse(aproxy)
route=xmldoc.getElementsByTagNameNS("http://www.bea.com/wli/sb/stages/publish/config", 'route')[0]
print type(route)
<type 'instance'>
print route.__class__
xml.dom.minidom.Element
import inspect
inspect.getmembers(route, predicate=inspect.ismethod)
