I'm a C++ and Boost newbie, and no regex guru, so don't quote me either :-) One thing I notice in your expression is a \t character following the =. Isn't that only going to match a tab? The boost::regex flag 'match_not_dot_newline' might be relevant, but since this flag must be explicitly set, it looks like dots match newlines by default. Would something as simple as this work (assuming dots match newlines)?: boost::regex ln0("WORD_TO_FIND=(.*)$", boost::regex::perl ); This assumes that the match you're looking for runs to the end of the string, which isn't clear. I'm also not clear if you want to match a single word or multiple words. Would stripping out newlines and replacing them with spaces first (or even later) help?
