XML File Generation Issues using DBMS_XMLGEN

Question

Hi,
I am using DBMS_XMLGEN package in a stored procedure to generate an XML file on Oracle 10 G R2 .But, the problem is the format in which the file is generated.
CREATE OR REPLACE TYPE "state_info" as object (
"@product_type" Number
CREATE OR REPLACE TYPE prod_tab as TABLE OF "state_info";
CREATE OR REPLACE TYPE state_t as object (
"state_code" CHAR(2),
"state_info" prod_tab
CREATE OR REPLACE PROCEDURE get_xml_serviced_state (p_clob OUT clob)
IS
v_xmlctx DBMS_XMLGEN.ctxhandle;
v_str VARCHAR2 (1000);
BEGIN
v_str := 'SELECT state_t(a.st_cd,CAST(MULTISET(select veh_type_id from svcd_st where st_cd =a.st_cd)as prod_tab)) as "state_info"
from svcd_st a where a.st_cd in (select distinct st_cd from svcd_st) group by a.st_cd having count(*)>=1';
v_xmlctx := DBMS_XMLGEN.newcontext (v_str);
DBMS_XMLGEN.setrowsettag (v_xmlctx,'serviced_state');
DBMS_XMLGEN.setrowtag (v_xmlctx,NULL);
p_clob := DBMS_XMLGEN.getxml (v_xmlctx);
printclobout(p_clob);
EXCEPTION
WHEN NO_DATA_FOUND
THEN
NULL;
WHEN OTHERS
THEN
RAISE;
END;
SHOW ERRORS
Output :
<serviced_state>
<state_info state_code="VA">
<state_info>
<state_info product_type="2"/>
<state_info product_type="5"/>
<state_info product_type="9"/>
</state_info>
</state_info>
<state_info state_code="AB">
<state_info>
<state_info product_type="2"/>
<state_info product_type="5"/>
<state_info product_type="9"/>
</state_info>
</state_info>
</serviced_state>
Required it in below format:
<serviced_state>
<state_info state_code="VA">
<state_info product_type="2"/>
<state_info product_type="5"/>
<state_info product_type="9"/>
</state_info>
<state_info state_code="AB">
<state_info product_type="2"/>
<state_info product_type="5"/>
<state_info product_type="9"/>
</state_info>
</serviced_state>
I just need to put in all the rows under one single tag.Appreciate your early responses.
Thanks.

Your wanted XML output is NOT VALID...(try it yourself on http://tools.decisionsoft.com/schemaValidate/)
