XML function help needed

Question

I am inserting an xml doc into a table with a CLOB column and have a Query such as this inside a dbms_xmlgen function :-
SELECT XMLELEMENT("provider", XMLForest(DECODE(a1.CORP_ID,''D'',13478,''RR'',14450) as"provider-id"),
xmlagg(XMLELEMENT( "Employee", XMLForest ( a18.EMP_FIRST_NM "first-name", a18.EMP_LAST_NM "last-name" ),XMLELEMENT("enc", XMLATTRIBUTES ( 'PWE-IL' AS "measure-set"),XMLForest ( a110.PP_DESC as "enc-flag",a18.EMP_ID as "emp-id",a12.EMP_AUX_RECORD_NBR as "Employee-group-number") )))) as "provider" .
I want to supress the duplicated PROVIDER nodes in the resulting doc. If I remove the 'AS PROVIDER' tag, it takes the xml function XMLELEMENT on the first line as the NODE.
I am at my wits end trying to get the duplicate tag out of the way. Please help...
