You don't need compression, you need encryption or a digest if you want the users not to alter the contents. The easiest solution is to calculate a Digest over your XML file and store the digest into the main app. It then checks the digest of the XML file and if it does not match, refuses to run. Any change to the XML will change the digest and the user would have to recalculate the digest and add it to the main app to make it work again. That will stop if not J. Random Hacker then certainly Fred Foobar from messing with the XML file.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
