Agree that Regex carries an extra mental overhead. This is why i kept away from it for a long time. Early this year i needed to use it in one of my projects, so i decided to bite the bullet and read Mastering Regular Expressions book. Once you understand the reasoning behind regex, it's a lot less intimidating. These days i use eventually For coincidence, yesterday, i was writing code to parse raw text to extract some data. Initially i did manually but when i needed to extract a new field i realized things would get even worse. Than rewrote with regex. See diff here: https://www.diffchecker.com/NDDa9gpH IMO much better. Not saying that is easy or should be used at will. But once you learn the basics, regex is a valuable tool. For debugging i use http://regexr.com/ and rely on unit tests to ensure correctness Luiz
