如何找到两个XML文档之间的差异

Question

I want to compare two XML documents to find and show where is the difference
like diff utility in XCode.

I can retrieve and parse xml code using NSXMLParser in basic level,
and can tell 'they are not exactly same'

but I don't know how to tell 'where and which'.

Is there any open-source based library for this?

Thanks in advance.
