comparing 2 xml strings

Hello! I just would like to ask if there is any tool I could use to compare 2 xml strings. The tool must identify the differences between the 2 xml string: nodes that have been added, deleted, updated, etc. Please help. Thanks a lot.

Seems like you have to write your own... this link would give you some tips from xslt point of view.
IMHO

Thanks! However, I need to compare the 2 xml strings from the backend and not using xslt. Do you have other suggestions?! thanks a lot!

Also, a viable alternative would be to use the Diff class from XMLUnit.
