Referencing REGEXP_REPLACE capture in other function

Question

Here's the deal...
I've got a clob that I'm scrubbing with REGEXP_REPLACE to remove the instance of a specific string, then I want to use that string in a function call. I can see the string (on line 2 below) but can't get the function in line 3 to utilize it.
THE CODE
1 SELECT regexp_replace(wrk_clob, 'href=\s*"([^"]+)"',
2                    || '\1' || ':'
3                    || get_id_list(in_table, in_state, '\1')
4 INTO wrk_clob
5 FROM dual;
THE FUNCTION SPEC
FUNCTION get_id_list(
               in_table VARCHAR2,
               in_state VARCHAR2,
               in_doc_name VARCHAR2)
                         RETURN VARCHAR;
If I hardcode the value from line 4 into the in_doc_name position it returns properly. However, it does nothing - because '\1' does not point to any data - with this reference.
Any ideas where to go with this?
Thanks.

Look here:
SQL> with t as (select '"111111" href="111"222' str from dual)
  2  select regexp_replace(str, 'href=\s*"([^"]+)"', '\1:'||decode(1,2,'asd','qwe')) yours,
  3         regexp_replace(str, 'href=\s*"([^"]+)"', '\1') yours2,
  4         regexp_replace(str, '.*?href=\s*"([^"]+)".*', '\1') mine,
  5         regexp_substr(str, 'href=\s*"([^"]+)"') subs1
  6          from t
  7  /
YOURS               YOURS2          MINE SUBS1
"111111" 111:qwe222 "111111" 111222 111  href="111"
SQL> If any questions rest - ask.

Whereas the piece that I have currently - regexp_replace(wrk_clob, 'href=\s*"([^"]+)"', - will cut out what the pieces I don't want.Can you provide an example of wrk_clob, and the result - you expect to get with this regexp_replace?
