find me a xml formatting tool

I have two xml documents. They should be the same except for a few small changes. I need to compare them to find the changes. The problem is that one has had most of the linefeeds removed which makes it hard to read. I need to find a xml formatting tool that I can run both of these xml files through so it will be easier for me to compare them later and find the differences. You job is to find the tool and test it with the two files I have enclosed to make sure the tool does what I need it to do. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
