By choosing Tools > Web Settings > Database, I'm able to specify an Excel spreadsheet as a database and select an appropriate driver. Then, I can create an HTML form and have the form data written to the Excel spreadsheet. I can also create a web page with Database Results regions to display selected data stored in the Excel file.

I would like to do the same thing with an XML file. Does anyone know if this is currently possible, and if so, how it can be done? I assume I'd need an XML driver similar to the Excel driver provided.
