i have used XMLAttributes to get the value
SELECT XMLELEMENT (

XMLAttributes ('1' as "TranNum",

from DUAL) as "PrcDate"),
XMLFOREST (
a.PAYMENT_ID AS "PmtID"),
XMLFOREST (
a.ACK_TRANSACTION_RECEIVER AS "Name1"),
XMLFOREST (
to_char(a.VALUE_DATE,'yyyy-mm-dd') as "ValueDate" ),
XMLFOREST (

XMLFOREST (
