So I was trying to use regular expression properly the other day, but even the basic stuff that I remembered from working with Perl had all but been lost in the depths of time. So I am pleased to come across this little bit of of software: RegEx Coach. Going to be trying it out over the next few days. Oh and if anyone woud like to tell me why there reg-ex isn’t standards compiliant with either POSIX or unix style regex I would be grateful.
