Select CLAUSE error using CURSORS & XSU.Please SEE.

Question

Hi,
I need to create NESTED XML using the DBMS_XMLQuery package.
I was instructed to use this for a Test purpose:
SQL> set long 40000
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
But am getting the error
DBMS_XMLQUERY.GETXML('SELECTDEPTNO'||'CURSORIS(SELECTEMPNOFROMEMPEWHEREE.DEPT=D.
<?xml version = '1.0'?>
<ERROR>oracle.xml.sql.OracleXMLSQLException: ORA-00923
: FROM keyword not found where expected
</ERROR>
CAN SOMEONE PLEASE Tell me WHAT I HAVE OVERLOOKED??

Do not forget to put spaces in the SQL string that you create at appropriate places (you forgot to put a space just before your FROM keyword).
SQL> set long 4000
SQL> select dbms_xmlquery.getXML('select deptno,' ||
  2  'cursor(select empno from emp e where e.deptno = d.deptno) EMPLOYEES' ||
  3  'from dept d where d.deptno = 10')
  4  FROM DUAL;
DBMS_XMLQUERY.GETXML('SELECTDEPTNO,'||'CURSOR(SELECTEMPNOFROMEMPEWHEREE.DEPTNO=D
<?xml version = '1.0'?>
<ERROR>oracle.xml.sql.OracleXMLSQLException: ORA-00923: FROM keyword not found w
here expected
</ERROR>
