Add a for each script to loop through HTTPService?

Question

I'm using Flash Builder 4 with the Flex 4.1 SDK.  I want to add a "for each" script to loop through my HTTPService XML file so only each nepName displays only once in my dropdown list.  In my XML file I have multiple records associated with nepName.  I would like ALL the records associated with each nepName to populate in my datagrid when it is selected from the dropdown.  Currently in my dropdown there is a nepName entry for each XML tag.  I hope I was able to explain that well enough. I'll try to put my code below so you can see everything I'm working with.
MXML:
<?xml version="1.0" encoding="utf-8"?>

               creationComplete="nepInfo.send()">
    <s:layout>

($file, pwd);Assuming "pwd" is meant as the current directory, here a small example :
TEST@db102 SQL> create or replace procedure test_proc (p1 varchar2, p2 varchar2)
  2  is
  3  begin
  4     dbms_output.put_line (p1||' '||p2);
  5  end;
TEST@db102 SQL> /
Procedure created.
TEST@db102 SQL> exit

$ cat test_proc.sh

exit
