Hi Mike,
Can you show me the code of how you parsed the XML and how you constructed the hash map. If I have some understanding of how that has been organized I think I can help you get to where you need to be. Right now I'm a little hazy as to what your hashmap is like... is it constructed in this fashion from your example:
0061399 maps to [1592345, 26728282, 29798989] ??
Regards,
Ryan Crosby
