How do you execute Xquery in ASP? Is is the same as using Xpath? Can someone give me an example?

Thanks Michael and all who answered my question! I didn't realize I would hit so many 'nerve endings'. Politics aside - organizations are making business decisions based upon incomplete and/or inaccurate information. Thanks again!
