Нужна помощь в извлечении данных с помощью XMLTable

Question

Мы пытаемся получить ns2: данные токена. SQL ниже не работает.

SELECT xml.* FROM xxce_test xx, 
         XMLTable(XMLNamespaces(DEFAULT 'http://www.xcec.com/AgileCard/xsd/12'),'/soapenv:Envelope/soapenv:Body/ns3:CardRefTokenAddRs/ns2:TokenizedData/' 
          passing xx.xml_data 
           columns 
            merchantId VARCHAR2(125) PATH 'ns2:Token' 
            ) xml 

xxce_test табличные данные (2columns):

ваш XPath является неправильным, и вы не объявили все пространства имен.

select /*+ cursor_sharing_exact */ 
xml.* 
    from xxce_test xx, 
     xmltable(
     xmlnamespaces(default 'http://www.xcec.com/AgileCard/xsd/12', 
         'http://schemas.xmlsoap.org/soap/envelope/' as "soapenv", 
         'http://www.xcec.com/AgileCard/xsd/12' as "ns2", 
         'http://www.xcec.com/AgileCard/wsdl/TokenizeCardsSvc-v1.0' as "ns3"), 
       '/soapenv:Envelope/soapenv:Body/ns3:CardRefTokenAddRs/ns2:TokenizedData' 
       passing xx.xml_data 
       columns 
        merchantid varchar2(125) path 'ns2:Token') xml
