dbuchanan,
You were asking about predetermining the name of the XML data file that gets generated when you submit data from Acrobat.
The name of the XML data file should always be the name of the file. Therefore, if the PDF file is named "test.pdf", the data file should end-up being "test.xml". The only catch is that if the form is opened in a browser, it means that it's been saved locally in a temporary folder
and with a temporary file name. That's when you start getting an XML data file that's named something like "TGA123DE.xml".
I know this may not necessarily solve your problem but I think it may at least explain why you're seeing different (unpredictable) XML data file names.
