Filter XML based on another xml using XSLT 1

Question

How do we filter an xml document based on another xml document. I have to remove all the elements which are not there in the lookup xml. Both the input xml and lookup xml ha

Answer 1

Hmmm, you're sort of talking about merging (assuming your filter doc is variable). There's a couple of possibilities which vary with the language you're implementing all of this in. Could you provide more info about the app?

Otherwise I suggest a quick google on "xslt +merge" and see if some result there grabs you.
