这是我的 SQL。我似乎无法从这件事中得到一个单一的值(value)。仅当我删除所有 xmlns 属性时它才有效。

我认为问题在于此 xml 包含 2 个默认 namespace ,一个附加到 Response 元素,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>
<Shipment xmlns="http://www.ups.com/XMLSchema/XOLTWS/Track/v2.0">
<InquiryNumber>
<Code>01</Code>
<Description>ShipmentIdentificationNumber</Description>
<Value>1ZA50209234098230</Value>
</InquiryNumber>
<ShipperNumber>A332098</ShipperNumber>
<ShipmentAddress>
<Type>
<Code>01</Code>
<Description>Shipper Address</Description>
</Type>
<Address>
<AddressLine>123 HWY X</AddressLine>

<CountryCode>US</CountryCode>
</Address>
</ShipmentAddress>
<ShipmentWeight>
<UnitOfMeasurement>
<Code>LBS</Code>
</UnitOfMeasurement>
<Weight>0.00</Weight>
</ShipmentWeight>
<Service>

<Description>UPS GROUND</Description>

</Shipment>
</TrackResponse>'

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

最佳答案

正如@marc_s 所说,您忽略了 xml 命名空间。 Here is a sql fiddle example .这给 X,我认为这就是您所需要的。 Read this article for more .注意:*:TrackResponse[1]/*: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
