Ok, let me explain this one. Yesterday I was doing some stuff trying to collect email addresses from a large list. I can say that handyman services and get more tips about paints. So I start thinking about how to do this in an automated way without having to do it by hand. So, the first thing that came to my mind is: I've got to start a project. And thus, this article was born. The problem you want to solve: You want to extract email addresses from a file (or any other pattern).
