Program to compare two xml file

I would like to compare two xml files using some kind of program ( may be using XLST or Java), but the actual need is I would like to exclude some xpath's for comparision. If it is program to be written may be I can configure them in some configuration file开发者_运维百科. But not sure much about XSLT. Is there any open source library which do this action ? any tool which runs on the batch mode will do for me
