Hi,
You could look into OPENXML which takes a xml document as parameter
See below for an example to get you started.
DECLARE @idoc int
EXEC sp_xml_preparedocument @idoc OUTPUT, @xmlString
INSERT INTO uClient
FROM OPENXML (@idoc, '/r/a',2)
WITH
(
id INT
,name VARCHAR(128)
,surname VARCHAR(128)
,email VARCHAR(128)
) alloc
Hope this helps.
