Re: [Boost-Users] Re: regex: flag for "global" search?

The boost::regex_search example bumps the start to march through the
sub-expressions and the boost::regex_grep examples demonstrate using the
'callback' for each term.

I was kinda hoping the library provided a "convenience version" that would
take something like "(\\w+)(?:\\.(\\w+))*" and populate the match_results
as if the terms had been expanded <e.g.> "(\\w+)(?:\\.(\\w+))?(?:\\.
(\\w+))?(?:\\.(\\w+))?"</e.g.>  Perhaps to some arbitrary limit?

Oh well, given the riches provided, a little while loop now and then is
surely a small price to pay.  ;)

Thanks for the response.  I'm continually amazed at the ethos fostered by
Boost group members.

Use boost::regex_grep. The boost::regex_search only finds the first match.
