weather and xml

I'm working on a program that retrieve weather 'FORECAST' from WUNDERGROUND.COM

I think I have finally worked out the layout of the datastructures, but now I'm getting
RNF0376
Total length 46856810 of data item SFORECA... exceeds
16,773,104 bytes.

The XML file is really not all that big. I have a significally larger XML that I am using for another process with no issue. My weather xml file is 10343 bytes my other xml file is 10210510 bytes
I'm not really sure how to go about resolving this issue.
