I need a Regual Expression what return how many numbers is in a string.. String can be like that: a2j5j32h56..
I try some expression.. But didn't work like i want.. Can anyone help me pls ?

$count(a2j5j32h569,0,1,2,3,4,5,6,7,8,9)
or with regex:
$regex(a2j5j32h569,/\d/g)

I'm not sure which is faster.

$count is faster, especially when it comes to long strings.

DOoh.. It was easy.. Collective&Online <- Thanks for fast reply
