Question

我有以下xml值，它存储在request_xml列中，它是clob数据类型：

  <?xml version='1.0' encoding='utf-8'?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
  <soapenv:Body>
    <ns:updateRechargeTicketResponse xmlns:ns="http://service.soap.CDRator.com">
      <ns:return xmlns:ax232="http://core.result.service.soap.CDRator.com/xsd" xmlns:ax233="http://core.data.soap.CDRator.com/xsd" xmlns:ax230="http://payment.result.service.soap.CDRator.com/xsd" xmlns:ax228="http://data.soap.CDRator.com/xsd" xmlns:ax231="http://result.service.soap.CDRator.com/xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ax230:RechargeTicketResultDTO">
        <ax233:id xsi:nil="true"/>
        <ax232:code>0</ax232:code>
        <ax232:description>SOAP_GLOBAL_SUCCESS</ax232:description>
        <ax232:serviceUser xsi:nil="true"/>
        <ax232:success>true</ax232:success>
        <ax232:translationTag>SOAP_GLOBAL_SUCCESS</ax232:translationTag>
        <ax230:rechargeTicket xsi:type="ax228:RechargeTicketDTO">
          <ax233:id>201505131421267777</ax233:id>
          <ax233:billingGroupId>201505071857272816</ax233:billingGroupId>
          <ax233:code>BALANCE_DIRECTDEBIT</ax233:code>
          <ax233:dateCreated>2015-05-13</ax233:dateCreated>
          <ax233:dayOfMonth>0</ax233:dayOfMonth>
          <ax233:nextRechargeDate xsi:nil="true"/>
          <ax233:rechargeAmount>10.0</ax233:rechargeAmount>
        </ax230:rechargeTicket>
      </ns:return>
    </ns:updateRechargeTicketResponse>
  </soapenv:Body>
</soapenv:Envelope>

我想从中提取值。我使用了以下查询，但它没有返回任何内容。我收到错误

ORA-19228: XPST0008 - undeclared identifier: prefix 'ax230' local-name 'ax230:rechargeTicket'
19228. 00000 -  "XPST0008 - undeclared identifier: prefix '%s' local-name '%s'"

这是我的查询

您的命名空间与源XML和查询不匹配

'http://data.soap.CDRator.com/xsd' as "ax233"

VS

xmlns:ax233="http://core.data.soap.CDRator.com/xsd"

尝试从您的来源中删除core.或将core.添加到XMLNAMESPACES的{{1}}。

修复错误：

ax233

您缺少ax230的名称空间声明，因此需要添加XMLNAMESPACES：

ORA-19228: XPST0008 - undeclared identifier: prefix 'ax230' local-name 'ax230:rechargeTicket'
19228. 00000 -  "XPST0008 - undeclared identifier: prefix '%s' local-name '%s'"

如果查询格式更好，您可能也会发现它更容易（除非您有理由按照自己的方式进行）。有关示例，请参阅以下内容：

'http://payment.result.service.soap.CDRator.com/xsd' as "ax230",
