[英]Given the following XML in SQL Server, how do I get a value?
Here is my SQL. 这是我的SQL。 I cannot seem to get one single value out of this thing. 我似乎无法从这件事中获得一个单一的价值。 It only works if I remove all of the xmlns attributes. 它只有在我删除所有xmlns属性时才有效。
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. 我认为问题是这个xml包含2个默认命名空间,一个附加到Response元素,另一个附加到Shipment元素。
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>

select Svc.Dsc.value('(/TrackResponse/Shipment/Service/Description)[1]', 'varchar(25)')
from @xml.nodes('/TrackResponse') as Svc(Dsc)
As @marc_s said, you are ignoring xml namespaces. 正如@marc_s所说,你忽略了xml命名空间。 Here is a sql fiddle example . 这是一个sql小提琴的例子 。 This gives X , I think that is what you need. 这给了X ,我认为这就是你需要的。 Read this article for more . 阅读本文了解更多信息 。 Note : *:TrackResponse[1]/*:
in the xpath
注意: *:TrackResponse[1]/*:
在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
Two problems: 两个问题:
<shipment>
element 你公然忽略了<shipment>
元素上定义的XML命名空间 Try this: 试试这个:
-- 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: 给我一个结果:
UPS GROUND
