Creating Primary-Foreign Keys when importing XML into MS Access

Hello,

I have an XML file given to me structured similarly to the one listed ( I can't post original XML).  I would like to import it into MS ACCESS.  It imports correctly into many tables but it doesn't add the Primary key of <RID> into the child tables as a foreign key.  In reading a few articles some say you have to parse things manually while others seem to suggest that creating a transform or schema may allow ACCESS to automatically provide the parent/child - Primary/Foreign Keys.  Can anyone point me in the right direction?  Custom Code or ?

 
<Record>
<RID>1</RID>
   <Person>
      <Name>John Does</Name>
      <Address>Main St</Address>
   </Person>
   <Person>
      <Name>Jane Doe</Name>
      <Address>Don't Walk</Address>
   </Person>
</Record>

<Record>
<RID>2</RID>
   <Person>
      <Name>Mike Smith</Name>
      <Address>Walk St</Address>
   </Person>
   <Person>
      <Name>Jane Doe</Name>
      <Address>Don't Walk</Address>
   </Person>
</Record>

Often times when importing data, I prefer to put it into a temp table first (or set of temp tables).  This allows me to "fix it up" and make sure everything's the way I want it, then you can INSERT INTO the final destination table, which would have the PK/FK columns and RI and such already defined.

Provided the temp table and final table column structures are the same, the INSERT statement is quite simple:

INSERT INTO ParentFinalTable SELECT * FROM ParentTempTable;
INSERT INTO ChildFinalTable SELECT * FROM ChildTempTable;
DELETE FROM ParentTempTable;
DELETE FROM ChildTempTable;

I've never really had good luck with the XML import feature of Access unless the incoming data was very simple. I ended up using the XMLDocument (part of the Microsoft XML library), which lets me open my incoming XML file and examine the structure, and then parse it as needed. There are many tutorials on use XML and such ...

Still, I use the temp table method suggested by Jack above. I parse my XML and insert to temporary tables, and then use standard VBA and SQL to move that to my live tables.
