Suppress Row Num from XML output

Question

Hi there,
Is possible to generate the output following without using style sheet ?
a) remove <ROW num="10">
b) to change the tag Code <COMM NULL="TRUE"/> to <COMM><COMM/>
Thanks

result := DBMS_XMLQuery.getXML(queryCtx);
INSERT INTO temp_clob_tab VALUES(result);
-- Now you can use the result to put it in tables/send as messages..
ShowClobContents(result);
DBMS_XMLQuery.closeContext(queryCtx); -- you must close the query handle..

Hi Ramesh,
Thanks for your reply. If I tried using DBMS_XMLGEN, I get the following output which is closer to the output that I want. How do i show the null value as <COMM></COMM> ?
Thanks
