XML index in bfile

Question

I tried to create intermedia text index on XML saved in a bfile, the creation had no problem, but if I use WITHIN clause to query the data, always return 0 rows. When I saved XML in CLOB, everything was ok. Could somebbody tell me why? How can I do that?
Thanks

Thanks. I tried as following, but it didn't work
create table bfilexml (id number primary key,info bfile);
insert into bfilexml values (1, bfilename('XML',test.xml));
insert into bfilexml values (2, bfilename('XML',test2.xml));
commit;
exec ctx_ddl.drop_section_group('xmlgroup');
exec ctx_ddl.create_section_group('xmlgroup','xml_section_group');
exec ctx_ddl.add_zone_section ('xmlgroup','name','<ename>');
exec ctx_ddl.add_zone_section ('xmlgroup','address','<addr>');
create index idx_bfilexml on bfilexml(info) indextype is ctxsys.context
parameters(filter ctxsys.null_filter section group xmlgroup');
the test.xml is
<ename>martin jones</ename>
<addr> 138th street</addr>
the test2.xml is
<ename> Mark Scott </ename>
<addr> 65 broadway </addr>
But when I do
SQL> select id from bfilexml where contains(info,'martin')>0;
ID
1
SQL> select id from bfilexml where contains(info,'martin within name')>0;
no rows selected
the WITHIN clause didn't work
