How to extract a number from a text column

Dear all,

I would like to extract a number from a text-column which contains many other numbers.

Example => Date: 01.01.2024 / 11:55:22 submitted by example company XY 123/456/789 80 1.111.111,50 81 222.222,22

Number to extract => 1.111.111,50 & 222.222,22

I always need the number following ‘80’ and ‘81’. But not all columns contains that numbers.

Does it work with the ‘column expression’ node?

I have no idea how to do this.

Thank you in advance if you can help!
