SQL Server 2005 with XML Namespaces - Query Multiple Nodes and Properties - sql

Question

I have the following XML and code and can pull back the AccountNumber and Status. I also need to pull back...
The ID property of the MFRRequest
Several elements from the CaseInformation node
I am not sure how to get the ID property and I'm wondering... can I get all of this information (from multiple nodes) back in the same query?
Thank you!

Answer 1

Try something like this:
;WITH XMLNAMESPACES('http://XXX.Schemas.OrderRequest/2' AS p)
SELECT
MFRRequestID = Y.i.value('(#id)[1]', 'int'),
RequestStatus = Y.i.value('Status[1]', 'varchar(10)') ,
AccountNumber = Y.i.value('p:AccountNumber[1]', 'varchar(10)'),
ReferralDate = CIF.value('(ReferralDate)[1]', 'varchar(25)'),
CaseInfoType = CIF.value('(Type)[1]', 'varchar(25)')
FROM
#doc.nodes('/p:OrderRequest/p:RequestItems/p:MFRRequest') AS Y(i)
CROSS APPLY
i.nodes('p:CaseInformation') AS Tbl(CIF)
Basically, once you have the <p:MFRRequest> XML element in your Y(i) pseudo-table, you can then again use a second call to .nodes() to get the (possibly multiple) <p:CaseInfomration> nodes and use .value() calls on this new second pseudo-table to extract single bits of information from it.
