Wrong XML Format

I’m trying to import an XML file someone gave me, but I can’t even get to the Import Field Mappings dialog. FileMaker says there’s an unknown element in the document.

FileMaker can import only XML that’s in the FMPXMLRESULT grammar. If you got the XML document from some source other than FileMaker, it’s very unlikely to conform to FMPXMLRESULT. You’ll need to apply a stylesheet to the XML as you import it to transform it into valid FMPXMLRESULT XML.
