>>>>>Hey gang,
>>>>>Here is my situation - I am attempting to build a generic Crystal Reports class where the end-user provides a path to the .rpt file, a path to an .xml file, and other options on how to export the report. A requirement is for the .xml file to have an external schema.

Glad to hear it works. I also use InferSchema.
