microsoft has xml diff , patch tool can use in .net application. microsoft provides sample gui tool written in c# uses library. can download gui source code installer here.

i don't have particular advice on using xml diff library powershell. using .net libraries powershell whole other topic, can find information on online. if not committed powershell, perhaps use c# or vb.net instead, in gui tool. if don't need write own script automate process, can use gui tool diff xml files on as-needed basis.
