最后是提取值：但没有用！请帮忙

如何使用XmlTable

您需要向下/到特定的XML标记/节点

 SELECT *
   FROM XMLTable('$dat//xmlpath' --the path to the node you want to start reading from
                   PASSING your_xml_node AS "dat"
                   COLUMNS
                       vcol NUMBER PATH 'col_path', --from your given node
                       ...etc
                    ) ;

对于要读取的每个XML值，需要在COLUMNS下添加一列，并将其映射到给定XML节点中的路径

你可以在网上阅读更多

编辑我使用了您在OP中列出的XML，下面是如何做到这一点我没有访问您的模式的权限，因此我使用*来查询任何模式/名称空间

在处理XML时，最重要的是路径，没有得到任何结果的原因是因为路径中的某个地方出错了。我花了一段时间才明白这一点，祝你好运：

      FROM XMLTABLE (
              xmlnamespaces (

谢谢你的帮助。我做了以下工作，效果很好！！它解决了

选择x.UPDATEDESCRIPTION，x.UpdateDateTime进入l_响应_消息，l_响应_结果从…起从双t中选择XMLType.createxmll_clob_响应xml， xmltable xmlnamespaces 'http://ws.aramex.net/ShippingAPI/v1/"作为e,， 'http://schemas.microsoft.com/2003/10/Serialization/Arrays"作为一个,， 'http://schemas.xmlsoap.org/soap/envelope/"至于,，违约'http://ws.aramex.net/ShippingAPI/v1/' , 's:Envelope/s:Body/ShipmentTrackingResponse/TrackingResults/a:KeyValueOfstringArrayOfTrackingResultmFAkxlpY/a:Value/TrackingResult[1]' 传递t.xml 柱 UpdateDescription varchar2128路径“UpdateDescription”， UpdateDateTime varchar2128路径“UpdateDateTime” x； dbms_output.put_line'The UpdateDescription=>'|| l|u response_消息；

dbms|u output.put_line'The UpdateDateTime=>'|| l|u response_result

谢谢你的帮助，但是默认的名称空间呢，我的问题就在这里。你能举个例子吗？我做了如下操作：选择EXTRACTl_resp_xml，//s:Envelope/s:Body/node，l_NAMESPACE_SOAP从dual提取l_resp_xml；然后：从xmltablexmlnamespaces的http://ws.aramex.net/ShippingAPI/v1/“作为一名律师，”http://schemas.microsoft.com/2003/10/Serialization/Arrays"作为n,，“/ShipmentTrackingResponse/a:TrackingResults/n:KeyValueOfstringArrayOfTrackingResultmFAkxlpY/n:Value/n:TrackingResult[1]”传递l_resp xml列更新描述VARCHAR2128路径“n:UPDATEDESCRIPTION[1]”xx；DBMS|u OUTPUT.put_line'Result>updatedescription='|| l|u response_message；但不幸的是没有用！！上面说找不到数据！！很高兴能帮上忙如果我的帖子确实回答了你的问题，请把它标记为一个回答，以帮助以后会来这里的其他人
