regular expressions? Hmmm... sometimes is it usefull to know them but most time you allways use the same. I have used regex quite often but I woulnd't say that I am good with it. I don't like it at all and I think there are more important things to know than regex.

But in validation of formulars or data its very usefull. I think allmost every professional form is validated with regex. ASP.NET using it.

But at all: Try to do an expression when you need it and save it. You will use them hopefully all more than once. But dont waste your time with RegEx!

Best Regards!
