Using xmlgen in a trigger -HELP

Question

We are trying to use xmlgen in a trigger, actually a insteadOf on a view but that is really secondary.
The problem we have is that xmlgen doesnt seem to work from a trigger or any other background process. There is no reall erro messgae it just fails.
Has anyone used xmlgen from a trgigger??

Can't this be done.....
create or replace trigger audit_EMP_DTL
before update or delete or insert
on EMP_DTL
for each row
declare
pragma autonomous_transaction;
v_blockexists number := 0;
no_lock exception;
ReturnExp EXCEPTION;
begin
select     count(a.sid) into v_blockexists
from     v$session a
where     a.sid=(select     tab1.sid
          from     v$lock tab1, v$lock tab2
          where     tab1.block =1
          and     tab2.request > 0
          and     tab1.id1=tab2.id1
          and     tab1.id2=tab2.id2
if v_blockexists = 0 then
insert into audit_blocks(program_name) values ('No block yet');
commit;
RAISE ReturnExp;
end if;
EXCEPTION
WHEN ReturnExp THEN
NULL;
END;
