Need To Use An XML Schema To Export Data... Help

Well I have NO IDEA how to do this... so I'll just admit my ignorance up front.

Anyway I have some customer records that need to be sent off for mailing.

The printing company takes XML files.

They provided me with an XML Schema (.xsd file)

I need to take the data in my table and export it to an .xml file to send off.

I tried doing something like this at first:

WITH XMLNAMESPACES (DEFAULT 'urn:blah.blah.blah...')
SELECT *
FROM
(SELECT CONVERT(varchar, GetDate(),120) AS submit_date,
'999999' AS client_billing_id,
customers.FirstNm AS customer_first_name,
customers.LastNm AS customer_last_name,
.....blah...additional fields..
FROM customers
) As Offset
FOR XML RAW ('Customer'), ROOT('CustomerMailingList'), ELEMENTS
Now that worked pretty well, it gave me a file that was formatted in what appeared to be the proper XML style, and I could save it and it "looked right".

However, the printers said there were a few errors and sent back a .XSD schema file for me to use.

Sounds great... but I haven't a clue on how to use it.

I've seen a few articles on how to manage existing schemas and how to store data IN the database, but nothing on how to EXPORT data.

As I understand it I just want to take data in my customers table and use the schema as a template / file mapping document to dump it out to XML.

So... help? :)

Thanks
