SELECT ID,xt_code.CODE
FROM TEMP_SOAP_MONITORING_MSP sm
CROSS JOIN XMLTable(XMLNAMESPACES (
'http://core.result.service.soap.CDRator.com/xsd' as "ax2140_code"
),
'for $i in //ax2140:code return $i'
passing XMLType(sm.RESPONSE_XML)
columns "CODE" VARCHAR2(50) path '/') xt_code;

Answer 1

Use "ax2140" instead of "ax2140_code" in the query.
