Re: ExportXML

This is a repost from a couple of days ago. I didn't get any

knowing that it is a complete impossibility would be welcome news, if
only so I can stop hitting my head. :-)

I've got an Access 2003 db that has many different relationships
between
tables, for example, books <-> book_author <-> authors <->
author_institution <-> institutions. If I do an export xml from the
toolbar, there is an option to choose which data to export, for
example:

- □ books
--- □ book_author
----- [Lookup Data]
------- □ authors
--------- □ author_institution
----------- [Lookup Data]
------------- □ institutions

Regardless of whether I export this way or via ExportXML in a VB
module, I get all the data, but I loose the node structure at certain
points. After trying everything I could think of, or find on the web,
I went back and examined the manual/toolbar option and noticed that
the relationships that fail to be maintained during the automated
process have a "[Lookup Data]" node between the parent and child node
(in the example above, between the book_author and author tables). So
I end up with something like:

<books>
<book_id>1</book_id>
<title>Run Rhonda Run</title>
<book_author>
<book_id>1</book_id>
<author_id>1</author_id>
</book_author>
<book_author>
<book_id>1</book_id>
<author_id>2</author_id>
</book_author>
</books>
<books>...more books...</books>
<authors>
<author_id>1</author_id>
<name>Rhonda Roads</name>
<author_instutute>
<author_id>1</author_id>
<institution_id>1</institution_id>
</author_institution>
</authors>
<authors>
<author_id>2</author_id>
<name>Robby Roads</name>
<author_instutute>
<author_id>1</author_id>
<institution_id>1</institution_id>
</author_institution>
</authors>
<authors>...more authors...</authors>
<instututions>
<institution_id>1</institution>
<name>Lincoln Elementary</name>
</institutions>
<institutions>...more institutions...</institutions>

I tried mucking around with relationships, but I'm always give the
same export options, regardless of table relationship definitions.

Does anybody have any suggestions on how to maintain the parent-child-
grandchildren-greatgrandchildren...
node relationships all the way down a tree during an xml export?

Thanks in advance!

This is relatively easy to achieve, (but not using the methods you
descirbe) but is it what you want? It's Northinds 2007's Employees
Table.

BTW: I'm sure Nancy said, "Just say No to LookUp Tables!"
