hi,Michael Kay,  oh yes, I think you are right. This file is used in
Microsoft's workflow product. But your knowledge on file format is
amazing! :) My task is to standardize the elements' and attributes'
name in thousands of these files. But Xml manipulation API cann't
change these names. I search the solution in web and people say it can
be done with XSLT. So I want to try. Actually the job is a little
complicated than this. But I think from this point I can find the way
myself. I just want to learn new things. If I cann't tackle it with
XSLT, I can still using regular expression to do the work. Thank you
very much!
