Formatting XML using DBMS_XMLGEN

Question

Hi.
Having Problems with generating XML out of a query using nested table types
-- Heres a test case
drop type test_tab
drop type test_type
drop type sub_type_tab
drop type sub_type
create or replace type sub_type as object ( "@a" varchar2(10), "@b" varchar2(10) );
create or replace type sub_type_tab as table of sub_type;
create or replace type test_type as object ( "@c" VARCHAR2(10), test sub_type_tab );
CREATE OR REPLACE TYPE test_tab AS TABLE OF test_type;
CREATE OR REPLACE VIEW test_view OF test_type
WITH OBJECT IDENTIFIER ("@c")
AS
SELECT
'C',
CAST(MULTISET(SELECT 'A', 'B' FROM DUAL) AS sub_type_tab)
FROM dual
The resultant XML out of DBMS_XMLGEN.GETXML is :
<?xml version="1.0"?>
<ROWSET>
<ROW c = "C">
<TEST>
<SUB_TYPE a="A" b="B"/>
</TEST>
</ROW>
</ROWSET>
As you can see as a consequence of the column collection type alias in the view
i have an extraneous <TEST> tag.
Does anyone know how I can remove this tag entry?
Thanks in advance

Marco,
I tryed to work with dbms_xslprocessor.clob2file,
that works good,
but what is in this matter with encoding UTF-8 ?
in my understandig, the xmltyp created should be UTF8 (16),
but when open the xml-file in xmlSpy as UTF-8,
it is not well ( german caracter like Ä, Ö .. ):
my dbms is
NLS_CHARACTERSET = WE8MSWIN1252
NLS_NCHAR_CHARACTERSET = AL16UTF16
NLS_RDBMS_VERSION = 10.2.0.1.0
-- test:
create table nh_test ( s0 number, s1 varchar2(20) ) ;
insert into nh_test (select 1,'hallo' from dual );
insert into nh_test (select 2,'straße' from dual );
insert into nh_test (select 3,'mäckie' from dual );
insert into nh_test (select 4,'euro_€' from dual );
commit;
select * from nh_test ;
S0     S1
1     hallo
1     hallo
2     straße
3     mäckie
4     euro_€
declare
rc sys_refcursor;
begin
open rc FOR SELECT * FROM ( SELECT s0,s1 from nh_test );
dbms_xslprocessor.clob2file( xmltype( rc ).getclobval( ) , 'XML_EXPORT_DIR','my_xml_file.xml');
end;
( its the same when using output with DBMS_XMLDOM.WRITETOFILE )
open in xmlSpy is:
<?xml version="1.0"?>
<ROWSET>
<ROW>
<S0>1</S0>
<S1>hallo</S1>
</ROW>
<ROW>
<S0>2</S0>
<S1>straޥ</S1>
</ROW>
<ROW>
<S0>3</S0>
<S1>m㢫ie</S1>
</ROW>
<ROW>
<S0>4</S0>
<S1>euro_€</S1>
</ROW>
</ROWSET>
