Question

我们正在尝试获取ns2：令牌数据。下面的SQL无效。

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表数据（2列）：

您的XPath是错误的，并且您没有声明所有名称空间。

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
