Hello,
I have the following text:
"abs(3).def(5).hhh(11)"
Is there an easy way for search for all the locations with "(" - number - ")".
I mean, all the places where there is a number between parenthesis.
I've try to use regexp but it was too complicate for me to understand how exactly it should be written.
Thanks.

Ran in:
I'm sure there is a regexp way to do this, but I find it easier to use pattern with its supporting functions. Here's how I would do it.
txt = "abs(3).def(5).hhh(11)";
pat = lookBehindBoundary("(") + digitsPattern + lookAheadBoundary(")");
extract(txt,pat)
ans = 3×1 string array
"3" "5" "11"

a="abs(3).def(5).hhh(11)";
regexp(a,'(\d+)')
