I'm having the same issue importing from an OLD goldmine database. Were you able to figure this out?
Allison Rice and AJEzk:
Thank you for the posts. I apologize for the delayed response.
From the help on Importing XML data:
"When the XML you’re importing does not conform to the FMPXMLRESULT DTD, you must apply an XSLT style sheet that transforms the XML into the proper grammar. The XSLT source may be a file or the result of an HTTP request."
To summarize, an XSL stylesheet is required to transform the XML source into FileMaker's own XML grammar. The stylesheet cannot be generic, because it must describe (a) the fields that FileMaker must import (or create, if importing into a new table) and (:) the path to the data feeding those fields.
