If A and B are your start and end points, then you want:

"A\\(.\\|\n\\)*?B"

You probably got thrown off by the fact that '.' matches anything
EXCEPT a newline.  Regexps are usually assumed to be line-based.

The '?' is there to make the '*' non-greedy, to prevent it from
matching everything between the first A and the last B in the whole
buffer.

The double '\'s are necessary in lisp code because it's interpreted as
a string before it's passed to the regexp engine.
