Often the answer to "compare this list with that list" is to populate a hash from one list and then look it up using items from the second list.

If you provide two lists with maybe 5 items in each and show us how you want to compare items from each list we may be able to help more. Trim each item down to just enough to demonstrate the problem btw.
