How to find specific text in a string?

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.

regular expression makes you relax :)

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+)')
