|Welcome to the Monastery|
But most of these things kan be read on the perlman or a good regex book.
It's good when you see a mistake and correct them, but these kind of things can be better bundled in a tutorial of some kind.
But good on you to correct mistakes made earlier.
I sometimes use some solutions and help others with sharing my solutions. And sometimes I realize there's a better way to do it and my way isn't that good way to do it.
But hey I'm learning. I program perl just as long as I joined perlmonks :-)
But that's tha advantage of PM I give my solution to a problem on PM and sometimes I get a Reply that corrects or improves my solution.
My opinions may have changed,
but not the fact that I am right
