Hello, everyone. There is a problem of attribute transfomation: I need to transfom rule's generated attribute to my own structure. I tried to parse mathematical formula and store it in std::vector in reverse Polish notation. Formula have form: math = as_string(*digit) >> (alpha) >> +(char_('+' | '-') >> math); rule<Iterator, std::string, space_type> math; Question #1: what type is it? I think that fusion::vector<std::string, char, std::vector<fusion::vector<char, std::string> > > but it seems it is not so. Question #2: how can I convert this structure, to mine (std::vector<std::string>)? -- View this message in context: http://boost.2283326.n4.nabble.com/Adapt-rule-s-attribute-to-my-own-Boost-Sp...
