Difficult thing to illustrate really. I'd suggest the best way to learn regular expressions is to use an interactive tool like Rubular (which lets you test regexes interactively in the browser - it passes the regex back over Ajax to the server and evaluates it using Ruby's regex parser). –Tom Morris 20:58, 24 July 2009 (UTC)
