Keep in mind that you may have to escape your surrounding tags to not be mistaken for regular expressions. The above expression typically does a non-greedy match on any text in between the two tags. It has to be non-greedy or it would search the first start tag and the last end tag and match everything in between, even other occurences of the tags.
Since I'm not familiar with Dreamweaver, I don't know if its F&R will select the tags, too. But it works the intended way in Eclipse.
