Question

Below code work in oracle 11g but oracle 12c release 1 give ora-00600 error. How can I make it database version independence?

DECLARE
  lxml xmltype;
    l_tag varchar2(30);
begin
  lxml :=
  xmltype('<responseObject>
             <error>That is not a valid request</error>
             <errorCode>A11</errorCode>
             <value>A</value>
           </responseObject>
           ');
 l_tag := 'responseObject/*';
  FOR test IN (
    select tag,
           VALUE
    FROM   xmltable(l_tag
             passing lxml
             columns
               tag VARCHAR2(128) path 'name()',
               VALUE VARCHAR2(128) path '.'
           ) t
  )
  LOOP
    dbms_output.put_line(test.tag || ' - ' || test.value);
  END LOOP;
end;
