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))
