How can I view and change the catalog for multiple reports at once

[craigaucott]

I need to re-point the catalog accessed by a few hundred reports on one of our servers.

I just wondered if anyone knows of any way to look at the catalog that is referenced by each report in a directory (via script), and then to update the catalog reference for any that need to change.

e.g. Run a script to show out of 100 reports in a folder, which ones reference Catalog A, then run another script and either use "if catalog = 'A' then catalog = 'B' else next" type logic, or even populate an array manually with the report names identified by the previous script and set the new catalog that way.

Hope someone at least understands what I need, and (hopefully) can help me out.

Thanks
