I can't get multi-dimensional array to work...

Hi,

I'm trying to create a multidimensional data structure.  However, id
doesn't seem to work past the 2nd dimension.

Here is my method:

def endElement(self, name):
        if name == 'row' :
            if not self.data.has_key(self.parent):
                self.data[self.parent] = {}
            elif 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))

I've tried all kinds of different variations, and I keep getting the
same result:

Traceback (most recent call last):
  File "sax.py", line 123, in ?
    parser.parse(open('report.xml'))
  File "/usr/lib/python2.4/site-packages/_xmlplus/sax/expatreader.py",
line 109, in parse
    xmlreader.IncrementalParser.parse(self, source)
  File "/usr/lib/python2.4/site-packages/_xmlplus/sax/xmlreader.py",
line 123, in parse
    self.feed(buffer)
  File "/usr/lib/python2.4/site-packages/_xmlplus/sax/expatreader.py",
line 216, in feed
    self._parser.Parse(data, isFinal)
  File "/usr/lib/python2.4/site-packages/_xmlplus/sax/expatreader.py",
line 315, in end_element
    self._cont_handler.endElement(name)
  File "sax.py", line 51, in endElement
    self.data[self.parent][self.child].append((self.creativeid,
self.clicks, self.imps))
KeyError: u'Pickup Trucks'

I have a lot of php experience - am I accidentally doing a "php thing"
in my code?

Thanks so much for your help!
