Извлечение данных из значения XML данных типа CLOB

Question

У меня есть следующее значение XML, который хранится в столбце request_xml и который CLOB тип данных:

<?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> 

Я хочу, чтобы извлечь значение из. Я использовал ниже запрос, но он возвращает nothing.I я получаю сообщение об ошибке, как

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

Вот мой запрос

Answer 1

Ваши Пространства имен не совпадают на исходном XML и ваш запрос

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

против

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

Попробуйте удалить core. из вашего источника или добавьте core. к вашему XMLNAMESPACES за ax233.

Чтобы исправить ошибку:

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

вам не хватает объявление пространства имен для ax230 так XMLNAMESPACES вам нужно добавить:

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

Вы также можете найти его проще если запрос отформатирован лучше (если у вас нет причин, по которым вы делаете это так, как вы). Для образца, смотрите ниже:

SELECT 
    t.error_code 
, t.error_description 
, t.code
