Using XSD Files

Hi, Im looking into alternatives for Rational Publishing Engine (RPE) and came across crystal reports. I basically need to find a reporting tool that will allow me to make reports from an XSD file repository? Is this something CR can do? I am using tools in the Rational SW Suite like ClearCase, ClearQuest and ReqPro. These IBM applications publish to a data service layer where all files are stored in an XSD file format, can CR be used to generate reports from these application's files?

Any help would be great!
