Rex to select number from string

Hi All,

I am trying to select numbers from a field using Rex, but I cannot seem to figure it out.

Basically the values that i have in the field are:

XX (432)
FH02 (2356)
YR01 (855553)

I want to be able to select the number in the () - this number can be of any length.

How can I do this?

Thanks!

You can try something like this

<your base search> | rex field=<fieldname> "\s\((?<number>[^\)]+)"

let me know if this helps!
