Flash AS3 reWrite

I need a change made to my operating AS3 that retrieves info from a .xml document on my server. The current AS3 Script calls the entire 13,000 possibilities from the .xml and requires a long wait time while retrieval. The retrieval works as written. I would like to have the AS3 Script call only the one (1) "Alpha Numeric" item from the .xml which is Ten Bits of information from an "Alpha Numerically Coded System". This project should take no more than 30 minutes time with rewriting and testing.
