Substr Function Help

Question

Hi
I have string i/p say : '1.5/15 N60'
i am using functions to split it like this
SUBSTR(NVL('1.5/15 N60', '000'),
1,
instr('1.5/15 N60', '/') - 1) Ans:1.5
SUBSTR(NVL('1.5/15 N60', '000000'),
instr('1.5/15 N60', '/') + 1,
2) Ans:15
REPLACE(SUBSTR(NVL('1.5/15 N60', '000000000'), instr('1.5/15 N60', 'N')+1, 3),
'N',
'') Ans:60
so for an input '1.5/15 N60' it is spliting like this 1.5 15 and 60
but for an input '1.00/10 NET 30' it should split like this 1.00,10 and 30 but it is splitting it in to 1,00,10 and ET.
and for inputs '2.00/15 NET 75 TIERS' it should split has 2.00,15 and 75
For input like 'N60' the functions should split it in to 0,0 and 60
For input like '10 DAYS NO DISCOUNT' o/p should be 0,0 and 10
Thanks&Regards,

This function could fit you need. It outputs a collection.
CREATE OR REPLACE TYPE NUM_TABLE IS TABLE OF VARCHAR2(30)
CREATE OR REPLACE FUNCTION GET_NUMBERS(
     STRING IN VARCHAR2
RETURN NUM_TABLE
AS
     IDX INTEGER;
     I INTEGER;
     L INTEGER;
     S VARCHAR2(30);
     OUT_TAB NUM_TABLE;
BEGIN
     OUT_TAB := NUM_TABLE();
     I := 0;
     L := 0;
     IDX := 0;
     LOOP
          IDX := regexp_INSTR(string,'([0123456789])+(\.[0123456789])?',IDX+L+1);
          IF IDX = 0 THEN
               RETURN OUT_TAB;               
          END IF;
          OUT_TAB.EXTEND();
          I := I+1;
          S := regexp_SUBSTR(string,'([0123456789])+(\.[0123456789])?',IDX);
          L := LENGTH(S);
          OUT_TAB(I) := S;
     END LOOP;
END;
