Great article, thanks.
It appears there's a small error though, Table 1 is missing for me.

A useful article, but I think you leap to the CROSS APPLY example with nodes a little early. I only understood this having first seen an example elsewhere that used .nodes against an xml @variable - and seeing that this in itself returns a table as its result set

Perfect example for .nodes. Can we take it one step further?

Instead of concatenating First Name & Last Name, can we produce the same rowset with two columns?
First Name
Last Name

So the results might read:

ID FirstName LastName
1 John Doe
1 Jack Smith
2 Bob Jones
2 Henrietta Jones
Bill Talada

If you want separate columns for first name and last name:


SELECT
ci.ClientID,
Person.query('.') AS Person,
Person.value('FirstName[1]','varchar(20)') AS First_Name,
Person.value('LastName[1]','varchar(20)') AS Last_Name
FROM
ClientInfo ci
CROSS APPLY
Info_untyped.nodes('/People/Person') AS People(Person)
;


Go
