    Note that CountZero's solution (based on your initial attempt, just adding the necessary "s" modifier) is doing a greedy match with '(.*)' -- this means that if there are two or more instances of '</div>' following the address section, the match will extend to the farthest one.

    Using '(.*?)' instead, to specify a non-greedy match, will do what you really want, though as pointed out already, you probably should be getting acquainted with proper HTML parsing. It takes a bit of learning to catch on, but in the long run a parsing module will lead you to quicker and better solutions than what can be done with regex matching.
