I think often when we talk of Regular Expressions or RegEx fear can be felt through the room and corridors feeding to it. I do agree that sometimes when we look at a competed Regular Expression it does rather resemble cartoon characters swearing at each other as there really does not seem to be enough real characters to make much sense. A lot is in how we right the RegEx, we can write the same expression in many ways such as \d for or digit or we can write it as [0-9]. Probaly, and this taste, [0-9] is more readable alt although a little longer. The great thing with Regular Expressions is once we can understand them then they are consistent across many Languages including PowerShell
