i'm tinkering with the powerful yet hostile (to me) regular expression, and I'm trying to find a way to analyze a list and report how many items are there before the last number which is different from zero.

0 15 0 0 0 0 0 20 0 0 15 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3 0

should report "1", because only one zero is after the last digit major than 0 ("3)

1 15 3 0 0 0 4 20 0 0 15 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

should report "21", because after the last number major than 0 (which is "15") there are 21 zeroes

Hi all,
i'm tinkering with the powerful yet hostile (to me) regular expression, and I'm trying to find a way to analyze a list and report how many items are there before the last number which is different from zero.
So, as an example, this

and this
1 15 3 0 0 0 4 20 0 0 15 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Can you help me out with this?
Thanks a lot!
