Henrik Nilsson's RegexReplaceActiviy

Henrik just made a great post about his RegexReplaceActivity. In it, he shows you how to capture the power of regular expressions (pun intended :).

While you're developing and tuning your regular expressions, it's handy to have a quick way to test them. I'd like to point you to a phenomenal online resource for testing regex patterns:

If you paste Henrik's sample regex pattern into the site, and then type a date into the text box, it'll highlight the pattern that's matched. Then, if you hold your mouse over the highlighted pattern, it'll show you the groups that are captured. Instant gratification!
