Since you're already using dictionaries, as an alternative solution you
could construct a single dictionary that is keyed on two-dimensional
tuples (also known as ordered pairs). Combine that with the setdefault
method to initialize new entries and you end up with something like
this:
def endElement(self, name):
if name == 'row':
entry = self.data.setdefault((self.parent,self.child),[])
entry.append(...)
