Querying XML within SQL Server with namespace - sql-server

Question

I'm trying to query some XML data that I was sent. I have followed various examples, but can't even address any of the elements beneath the root. I'm not sure what I'm missing. I've tried simply pulling the xml beneath /KitchenSupply/StoreInfo and nothing. Is the namespace the culprit for me not being able to return anything?
declare #myxmlinv as xml =
'<?xml version="1.0" encoding="utf-8"?>

declare #myxmlinv_table as table (
row_id tinyint,
inv_xml xml
);
insert into #myxmlinv_table(row_id,inv_xml) values('1',#myxmlinv);
Display the XML document and pull the IntId column: (doesn't work)
select i.row_id, i.inv_xml, i.inv_xml.value('(/KitchenSupply/StoreInfo/IntId)[1]','varchar(255)') as data_description
from #myxmlinv_table i
Attempt to use XMLNAMESPACES to display the XML document at the StoreInfo level: (also doesn't work)
WITH XMLNAMESPACES ('http://www.starstandards.org/STAR' as ks)
SELECT
XmlCol.query('/ks:KitchenSupply/StoreInfo')
FROM T;
Ideally, I'd like to use the nodes to extract all the data out and in to separate tables for querying.
KitchenOrders all within one table, CustomerRecord within another, etc.
Any ideas?

Answer 1

You need to use something like this:
-- define the XML namespace as the "default" so you don't have to
-- prefix each and every XPath element with the XML namespace prefix
WITH XMLNAMESPACES( DEFAULT 'http://www.starstandards.org/STAR')
SELECT
-- reach into the <KsRecord> subnode under <KitchenOrder>
ReceiptNo = XC.value('(KsRecord/ReceiptAmt/#RcptNo)[1]', 'int'),
CustName = XC.value('(KsRecord/ReceiptAmt/#CustName)[1]', 'varchar(25)'),
-- reach into the <CustomerRecord> subnode under <KitchenOrder>
CustomerLastName = xc.value('(CustomerRecord/ContactInfo/#LastName)[1]', 'varchar(50)'),
CustomerEmail = xc.value('(CustomerRecord/ContactInfo/Email/#MailTo)[1]', 'varchar(50)')
FROM
-- get a "virtual" table of XML fragments, one for each <KitchenOrder> node
#myxmlinv.nodes('/KitchenSupply/KitchenOrder') AS XT(XC)

Answer 2

Yes, it's the namespace. To get SQL Server to ignore the namespace you can use local-name:
SELECT *
FROM #myxmlinv_table
WHERE inv_xml.exist('//*[local-name()="KitchenSupply"]') = 1
