ORA-22813: operand value exceeds system limits when generation XML

Question

Hi All,
We are using Oracle 11GR2 database and I am trying to generate XML Files using SQL/XML Functions.
I am in the end of development and while testing I am facing this freaking issue. ORA-22813: operand value exceeds system limits.
SELECT XMLSERIALIZE(DOCUMENT DATA AS CLOB) AS DATA FROM (

FROM div_comm_mobility_info_vw di
WHERE di.region = r.region
) AS "Division_Data"))) AS DATA
FROM reg_comm_mobility_info_vw R GROUP BY region)
This is working fine for conditions where there is less amount of data, but when there is more data this query is failing.
I do not know what to do now. Is there any way of this limit or do I need someother mechanisms to generate XML Files.
The challenge is we need to generate XML Files and send the XML Data to an Interface which will use this data to display in a cell phone.
I am really frustated now as I am getting this error when I am testing for huge amount of data.
Appreciate if anyone can help me out ASAP.

You didn't give any feedback in your previous thread.
Did you try the approach suggested here in {message:id=10998557}, instead of using nested inline subqueries ?
