Aye, the construct I posted needs to be anchored (but not necessarily using ^ and $). It may be a waste to use that construct for single characters, but it's useful (necessary) for the use I described in my original post (i.e. To matche a sequence of characters that does not contain anything that matches a specified regexp). For example,

/<table>(?:(?!<\/table>).)*<\/table>/

(Not the best example, cause tables can be nested in HTML and for other reasons, but you get the idea.)
