Merge 2 XML files and modifying the attribute values

Question

I have two xml files. I want to merge them and make some arithmetic with a few attributes. Please provide some ideas. I am using a standard xslt http://informatik.hu-berlin.de/m

Answer 1

You can use XSLT and the document function. Document loads another xml file into the xslt processing. The example does only a simple arithmetic operation. You need to modify it.
