You are right: non-greedy matching takes care of a few cases. Still, what i said about regexps being unable to parse still stands. For instance, your perl-program would have problems with:
I admit, this (and some more cases i could cite) are fringe. Maybe the thread-O/P will never encounter any of these. But again, it is - in a strict sense - impossible to overcome all of these problems (some of them, yes, but not all) because a regexp engine cannot work as a parser.
I hope this helps.
