[Boost-users] tokenizing with xpressive

I'm trying to tokenize lines of a file using the included static regex.  I only care about the tokens indicated by s* = ...  When I use the sregex_token_iterator to parse the lines, I only get the last match for s2 and s3.
 
How should I change things so that I can get every match for s2 and s3 rather than just the last match?
 
sregex whitespace_regex = *_s;
sregex line_regex =
    whitespace_regex >>
    (s1 = +_d) >> whitespace_regex >>
    (
        +(
            '\"' >> (s2 = *~as_xpr('\"')) >> '\"' >>
            whitespace_regex >> ':' >> whitespace_regex >>
            '\"' >> (s3 = *~as_xpr('\"')) >> '\"' >>
            whitespace_regex
        )
        |
        +(
            '\"' >> (s2 = *~as_xpr('\"')) >> '\"' >>
            whitespace_regex
        )
    );
