We are trying to get XML element (TAG) value from the XML pay load.
Example.
Getting XML String from a web service and then converting into XML payload.
ora:parseEscapedXML(bpws:getVariableData('signOn_Out','signOnReturn'))
From this XML payload we are trying to get an element (Tag) value.
We are getting following error
Error in evaluate <from> expression at line "130". The result is empty for the XPath expression : "/client:TririgaProcessResponse/client:User/client:LastName".
