在 t-sql 内解析 Xml，从根内的多个级别使用 XQuery 选择器发出问题，并解析来自所选节点的值

Question

我对解析 Xml 中的值非常陌生，希望有一些 Xml (XQUERY/XPATH) 知识的人能向我解释如何解析以下 Xml 中的某些值 Xml 使用 t-sql。我将包括我所做的代码尝试，以表明我不只是要求别人为我做这件事。

给出以下 Soap Xml 响应：


    <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="urn:aah:remtp:schemas:PlaceOrderResponse:1.00">
       <SOAP-ENV:Body>
          <PlaceOrderResponse xmlns="urn:aah:remtp:schemas:PlaceOrderResponse:1.00">
             <StatusCode>0</StatusCode>
             <TextReply>Successful</TextReply>
             <PlaceOrderReplyMessage>
                <TransmissionId>aac1e254-bc05-4d69-b04d-31d5fead314e</TransmissionId>
                <ReplyOrder>
                   <TrackingId>aac1e254-bc05-4d69-b04d-31d5fead314e</TrackingId>
                   <CustomerAccount>A_TEST</CustomerAccount>
                   <CustomerOrder>aac1e254-bc05-4d69-b04d-31d5fead314e</CustomerOrder>
                   <ReplyGroup>
                      <LineNumber>1</LineNumber>
                      <ReplyItem>
                         <ReplyCode>0</ReplyCode>
                         <ReplyData>10</ReplyData>
                         <ReplyMsg>Successful</ReplyMsg>
                      </ReplyItem>
                   </ReplyGroup>
                   <ReplyGroup>
                      <LineNumber>2</LineNumber>
                      <ReplyItem>
                         <ReplyCode>0</ReplyCode>
                         <ReplyData>15</ReplyData>
                         <ReplyMsg>Successful</ReplyMsg>
                      </ReplyItem>
                   </ReplyGroup>
                </ReplyOrder>
             </PlaceOrderReplyMessage>
          </PlaceOrderResponse>
       </SOAP-ENV:Body>
    </SOAP-ENV:Envelope>

并将 ReplyGroups 解析为 Table 变量（一旦我对 select 进行排序，这应该很容易 - 我认为）。

我试过以下方法：


    DECLARE @XmlDocument XML
    DECLARE @StatusCode VARCHAR(MAX)
    DECLARE @TextReply VARCHAR(MAX)
    DECLARE @CustomerOrder VARCHAR(MAX)
    
    SELECT @XmlDocument = '<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="urn:aah:remtp:schemas:PlaceOrderResponse:1.00">
       <SOAP-ENV:Body>
          <PlaceOrderResponse xmlns="urn:aah:remtp:schemas:PlaceOrderResponse:1.00">
             <StatusCode>0</StatusCode>
             <TextReply>Successful</TextReply>
             <PlaceOrderReplyMessage>
                <TransmissionId>aac1e254-bc05-4d69-b04d-31d5fead314e</TransmissionId>
                <ReplyOrder>
                   <TrackingId>aac1e254-bc05-4d69-b04d-31d5fead314e</TrackingId>
                   <CustomerAccount>A_TEST</CustomerAccount>
                   <CustomerOrder>aac1e254-bc05-4d69-b04d-31d5fead314e</CustomerOrder>
                   <ReplyGroup>
                      <LineNumber>1</LineNumber>
                      <ReplyItem>
                         <ReplyCode>0</ReplyCode>
                         <ReplyData>10</ReplyData>
                         <ReplyMsg>Successful</ReplyMsg>
                      </ReplyItem>
                   </ReplyGroup>
                   <ReplyGroup>
                      <LineNumber>2</LineNumber>
                      <ReplyItem>
                         <ReplyCode>0</ReplyCode>
                         <ReplyData>15</ReplyData>
                         <ReplyMsg>Successful</ReplyMsg>
                      </ReplyItem>
                   </ReplyGroup>
                </ReplyOrder>
             </PlaceOrderReplyMessage>
          </PlaceOrderResponse>
       </SOAP-ENV:Body>
    </SOAP-ENV:Envelope>'
    
            --  PlaceOrderResponse/StatusCode
    SELECT @StatusCode = CONVERT(VARCHAR(MAX), @XmlDocument.query('/PlaceOrderResponse/StatusCode'))
    
            --  PlaceOrderResponse/TextReply
    SELECT @TextReply = CONVERT(VARCHAR(MAX), @XmlDocument.query('/PlaceOrderResponse/TextReply'))
    
            --  PlaceOrderResponse/PlaceOrderReplyMessage/ReplyOrder/CustomerOrder
    SELECT @CustomerOrder = CONVERT(VARCHAR(MAX), @XmlDocument.query('/PlaceOrderResponse/PlaceOrderReplyMessage/ReplyOrder'))
    
    
    
    --SELECT @StatusCode As StatusCode, @TextReply As TextReply, @CustomerOrder As CustomerOrder
    --INSERT INTO @ResponseLines(LineNumber, ReplyCode, ReplyData, ReplyMessage)
    SELECT @XmlDocument.query('/PlaceOrderResponse/PlaceOrderReplyMessage/ReplyOrder/ReplyGroup')

不幸的是，在此之后所有变量都是空的，我认为这是因为我没有从 selectors 中的根节点开始。此外，如果我删除两个 soap 信封节点和任何命名空间，这些值将被填充，但使用实际节点而不是每个节点内的值。

如果有人能告诉我，我将不胜感激：

如何从 <PlaceOrderResponse> 节点而不是根节点开始查询 Xml 以获得正确的节点
如何解析我正在查看的节点内部的值 (StatusCode, ReplyText, CustomerOrder)。
如何select 将多个 <ReplyGroup> 项放入 table 结构中。请注意 <LineNumber> 元素在 Xml 树层次结构中的位置高于与其关联的 <ReplyItem>。

Answer 1

您需要注意命名空间。在下面查看如何操作。

</SOAP-ENV:Envelope>';

;WITH XMLNAMESPACES('http://schemas.xmlsoap.org/soap/envelope/' AS [SOAP-ENV]
    ,'urn:aah:remtp:schemas:PlaceOrderResponse:1.00' AS ns2)
SELECT @StatusCode = c.value('(ns2:StatusCode/text())[1]','INT')

-- test
SELECT @StatusCode AS StatusCode
    , @TextReply AS TextReply

输出
