Question

我正在尝试从嵌套的xml标签中查询信息。尽管我进行了许多网络搜索，并尝试了所有发现的内容，但是没有在我想要的嵌套中指定确切的数字元素，没有任何东西能让我得到我想要的结果。

我要运行的代码是这样的：

DECLARE @XmlIN XML
SELECT @xmlin  = '
<ShippingScheduleResponse   xmlns="rrn:org.xcbl:schemas/xcbl/v4_0/materialsmanagement/v1_0/materialsmanagement.xsd">
  <ShippingScheduleResponseHeader>
    <ShippingScheduleHeader>
        <ScheduleReferences>
        <OtherScheduleReferences>
          <ReferenceCoded xmlns="rrn:org.xcbl:schemas/xcbl/v4_0/core/core.xsd">
            <ReferenceTypeCoded>Other</ReferenceTypeCoded>
            <ReferenceTypeCodedOther>HomeOwnerOccupied</ReferenceTypeCodedOther>
            <ReferenceDescription>N</ReferenceDescription>
          </ReferenceCoded>
          <ReferenceCoded xmlns="rrn:org.xcbl:schemas/xcbl/v4_0/core/core.xsd">
            <ReferenceTypeCoded>Other</ReferenceTypeCoded>
            <ReferenceTypeCodedOther>WorkOrderNumber</ReferenceTypeCodedOther>
            <ReferenceDescription>7456634</ReferenceDescription>
          </ReferenceCoded>
          <ReferenceCoded xmlns="rrn:org.xcbl:schemas/xcbl/v4_0/core/core.xsd">
            <ReferenceTypeCoded>Other</ReferenceTypeCoded>
            <ReferenceTypeCodedOther>SSID</ReferenceTypeCodedOther>
            <ReferenceDescription>293283</ReferenceDescription>
          </ReferenceCoded>
        </OtherScheduleReferences>
      </ScheduleReferences>
    </ShippingScheduleHeader>
  </ShippingScheduleResponseHeader>
</ShippingScheduleResponse>
'

SELECT

    RefLineValue = ref.value('@xmlns', 'varchar(300)'),
    RefTypeOther = ref.value('(ReferenceTypeCodedOther)[1]', 'varchar(50)'),
    RefDescription = ref.value('(ReferenceDescription)[1]', 'varchar(50)')
FROM
    @XmlIN.nodes('/ShippingScheduleResponse/ShippingScheduleResponseHeader/ShippingScheduleHeader/ScheduleReferences') AS XTbl(schref)
CROSS APPLY
    schref.nodes('OtherScheduleReferences/ReferenceCoded') AS XTbl2(ref)

我正在尝试将referenceTypeCodedOther和ReferenceDescription的值放入表中。

最好的情况是获取ReferenceTypeCodedOther的参考说明，该参考说明等于SSID，而不必放入硬编码的st.value('(//*:ReferenceCoded[7][1]//*:ReferenceDescription)[1]', 'char(200)')

任何帮助将不胜感激。谢谢

您的代码几乎是完美的：要从xml中提取值，您只需使用WITH关键字即可处理名称空间：

;WITH XMLNAMESPACES (
    'rrn:org.xcbl:schemas/xcbl/v4_0/materialsmanagement/v1_0/materialsmanagement.xsd' as ns1,
    'rrn:org.xcbl:schemas/xcbl/v4_0/core/core.xsd' as ns2)
SELECT
  RefTypeOther = ref.value('(ns2:ReferenceTypeCoded)[1]', 'varchar(50)'),
  RefTypeOther = ref.value('(ns2:ReferenceTypeCodedOther)[1]', 'varchar(50)'),
  RefDescription = ref.value('(ns2:ReferenceDescription)[1]', 'varchar(50)')
FROM
    @XmlIN.nodes('/ns1:ShippingScheduleResponse/ns1:ShippingScheduleResponseHeader/ns1:ShippingScheduleHeader/ns1:ScheduleReferences') AS XTbl(schref)
CROSS APPLY
    schref.nodes('ns1:OtherScheduleReferences/ns2:ReferenceCoded') AS XTbl2(ref)

结果：

现在您可以按RefDescription = 'SSID'

进行过滤
