Aaron's Web tip of the day. (by way of my friend skogie)
Rex V: an AJAX Regular Expression Validator
Basically, you can throw a mess of text at this thing, then enter a regular expression to evaluate, and it will tell you what matches, and what doesn't. More than that, it'll tell you precisely where the match borders are.. so if you're grabbing extra line breaks or spaces you don't want.. it'll show you why.
good stuff.
