Clearing unwanted Tags using XmlElement()

Question

Hi,
Using the following Select clause produces the flwg
XML Document:
SQL> SELECT dbms_xmlquery.getXML('select deptno, dname, '||
2 'cursor(select empno, ename, sal from emp e where e.deptno = d.deptno) employees '||
3 'from dept d where d.deptno in (10, 20)')
4 FROM dual;
DBMS_XMLQUERY.GETXML('SELECTDEPTNO,DNAME,'||'CURSOR(SELECTEMPNO,ENAME,SALFROMEMP
<?xml version = '1.0'?>
<ROWSET>
<ROW num="1">
<DEPTNO>20</DEPTNO>
<DNAME>RESEARCH</DNAME>
<EMPLOYEES>
<EMPLOYEES_ROW num="1">
<EMPNO>7369</EMPNO>
<ENAME>SMITH</ENAME>
<SAL>800</SAL>
</EMPLOYEES_ROW>
<EMPLOYEES_ROW num="2">
<EMPNO>7566</EMPNO>
<ENAME>JONES</ENAME>
<SAL>2975</SAL>
</EMPLOYEES_ROW>
</EMPLOYEES>
</ROW>
Is there a way to delete unwanted tag like
<Employees_Row num 1>......<.10>
Some one at this forum suggested to used XMLELEMENT(), XMLAGG() and XMLFOREST().Any ideas of how to use these,
I am presently using the
DBMS_XMLQuery.setRowTag(queryCtx,NULL);
but its not helpful when you have a long and nested XML
Any ideas please?

</SDIEXTRACT>You see the DEPO_NOSTRO_IND_ROW_num =1

These are the ones I'd like to clear.
Any suggestions please
