I haven't tested it, but superficially I'd suggest giving this a try:

def endElement(self, name):
if name == 'row' :
if not self.data.has_key(self.parent):
self.data[self.parent] = {}
if not self.data[self.parent].has_key(self.child):
self.data[self.parent][self.child] = []
self.data[self.parent]
[self.child].append((self.creativeid, self.clicks, self.imps))

That seems to have done the trick! I can't believe I spent all
afternoon trying to figure that out!! Thanks a million!

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(...)
