Can I select element number from table collection expression?

Question

Hi, I know I can use COLUMN_VALUE to select column values from table collection expression. Is there any way to select the number of the element as well? (with Oracle 11.2.0.1.0)
CREATE OR REPLACE TYPE plch_numbers_nt IS TABLE OF NUMBER;
DECLARE
   l_numbers   plch_numbers_nt
                  := plch_numbers_nt (10,
                                      20,
                                      30,
                                      40,
                                      50);
BEGIN
   -- This would be nice...
   FOR rec IN (SELECT COLUMN_VALUE, VALUE_INDEX FROM TABLE (l_numbers))
   LOOP
      DBMS_OUTPUT.put_line (rec.COLUMN_VALUE, rec.VALUE_INDEX);
   END LOOP;
END;

First of all, I would like to thank you all for your replies. I really appreciate your help.
The problem I'm trying to solve is more complicated than what I have shown so far. Right now I'm trying to decompose the problem into smaller problems. Maybe I should show you the full problem and hope that I still get a reply.
I have a spatial column with collections of geometries (SDO_GTYPE 2004) and I have a VARRAY column of objects. For each row, each geometry in the geometry collection has some information in one element in the VARRAY. So I have this table
-- +----+------------------+-----------------------------------------------------------------------------------+
-- | ID | GEOM_COLL        | GEO_INFO                                                                          |
-- +----+------------------+-----------------------------------------------------------------------------------+
-- | 98 | sdo_geom(2004)_1 | ((geo_info_1_1_1; geo_info_2_1_1; ...);(geo_info_1_1_2; geo_info_2_1_2; ...) ...) |
-- +----+------------------+-----------------------------------------------------------------------------------+
-- | 99 | sdo_geom(2004)_2 | ((geo_info_1_2_1; geo_info_2_2_1; ...);(geo_info_1_2_2; geo_info_2_2_2; ...) ...) |
-- +----+------------------+-----------------------------------------------------------------------------------+
--  ...and I need this
-- +----+--------------------+----------------+----------------+-----+
-- | ID | SDO_GEOM           | GEO_INFO_1     | GEO_INFO_2     | ... |
-- +----+--------------------+----------------+----------------+-----+
-- | 98 | sdo_geom(2001)_1_1 | geo_info_1_1_1 | geo_info_2_1_1 | ... |
-- +----+--------------------+----------------+----------------+-----+
-- | 98 | sdo_geom(2002)_1_2 | geo_info_1_1_2 | geo_info_2_1_2 | ... |
-- +----+--------------------+----------------+----------------+-----+
-- +----+--------------------+----------------+----------------+-----+
-- | 99 | sdo_geom(2002)_2_1 | geo_info_1_2_1 | geo_info_2_2_1 | ... |
-- +----+--------------------+----------------+----------------+-----+
-- | 99 | sdo_geom(2001)_2_2 | geo_info_1_2_2 | geo_info_2_2_2 | ... |
-- +----+--------------------+----------------+----------------+-----+
-- ...I need a flat version of the original table, if you will. My original plan was to convert the VARRAY values to rows and extract the geometries into rows. Then join both using their ROWNUMs. But this does not work as i need numbers that start at 1 for each ID and I'm not sure if ROWNUM will give me the right order. Hence my question for consecutive element numbers. I have no idea how to do it with SQL. I'm working on a PL/SQL solution right now. Sample code follows. Sorry for the length of this post.
