Given the following XML in SQL Server, how do I get a value? - sql

Question

Here is my SQL. I cannot seem to get one single value out of this thing. It only works if I remove all of the xmlns attributes.
I think the problem is that this xml contains 2 default namespaces, one attached to the Response element and one attached to the Shipment element.
DECLARE #xml XML
SET #xml = '<TrackResponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Response xmlns="http://www.ups.com/XMLSchema/XOLTWS/Common/v1.0">
<ResponseStatus>
<Code>1</Code>
<Description>Success</Description>
</ResponseStatus>
<TransactionReference />
</Response>
<Shipment xmlns="http://www.ups.com/XMLSchema/XOLTWS/Track/v2.0">

<Code>01</Code>

select Svc.Dsc.value('(/TrackResponse/Shipment/Service/Description)[1]', 'varchar(25)')
from #xml.nodes('/TrackResponse') as Svc(Dsc)

Answer 1

As #marc_s said, you are ignoring xml namespaces. Here is a sql fiddle example. This gives X, I think that is what you need. Read this article for more. Note : *:TrackResponse[1]/*: in the xpath
--Results: X
declare #xmlTable as table (
xmlData xml
)
insert into #xmlTable
select '<TrackResponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Response xmlns="http://www.ups.com/XMLSchema/XOLTWS/Common/v1.0">
...
</TrackResponse>'
;with xmlnamespaces(default 'http://www.ups.com/XMLSchema/XOLTWS/Track/v2.0')
select
x.xmlData.value('(/*:TrackResponse[1]/*:Shipment[1]/Package[1]/Activity[1]/Status[1]/Type[1])','varchar(100)') as all_snacks
from #xmlTable x

Answer 2

Two problems:
you're blatantly ignoring the XML namespace that's defined on the <shipment> element
your XQuery expression was a bit off
Try this:
-- define XML namespace
;WITH XMLNAMESPACES('http://www.ups.com/XMLSchema/XOLTWS/Track/v2.0' AS ns)
select
Svc.Dsc.value('(ns:Shipment/ns:Service/ns:Description)[1]', 'varchar(25)')
from
-- this already selects all <TrackResponse> nodes - no need to repeat that in
-- your above call to .value()
#xml.nodes('/TrackResponse') as Svc(Dsc)
Gives me a result of:
UPS GROUND
