To the best of my knowledge, the only built-in support for XML available
when using Access 2000 is the ability to save and open an ADO recordset
to/from an XML file. If you want to pursue this option, check out KB article
263247, "HOWTO: Obtain an ADO Recordset from XML".
I encountered what appears to be a bug where ADO will not correctly return
all records when the XML file uses the non-abbreviated format for empty
elements (<z:row ...></z:row>). I had to replace it with the abbreviated
format (<z:row ... />)
Alternatively, if you ask around in the XML/XSL newsgroups, someone might be
able to advise you on how to transform the XML into a format that the
built-in import tools would recognize, such as CSV or fixed-width.
