Answer 1

for example
select dbms_xmlgen.getxml('select empno, ename from emp where rownum <3') from dual
<?xml version="1.0"?>
<ROWSET>
<ROWSET>
  <EMPNO>1</EMPNO>
  <ENAME>123</ENAME>
</ROW>
<ROW>
  <EMPNO>9999</EMPNO>
  <ENAME>Tim</ENAME>
</ROW>                                                                                    
</ROWSET>      or
SELECT xmlelement("ROWS", xmlagg( xmlelement("ROW",xmlelement("EmpNumber", empno), xmlelement("EmpName", ename))))
FROM emp
WHERE rownum<3
<ROWS><ROW><EmpNumber>1</EmpNumber><EmpName>123</EmpName></ROW><ROW><EmpNumber>9999</EmpNumber><EmpName>Tim</EmpName></ROW></ROWS>
