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",

xmlreader.IncrementalParser.parse(self, source)

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!

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!
