c++ - Boost split not traversing inside of parenthesis or braces -

i try split following text:

std::string text="1,2,3,max(4,5,6,7),array[8,9],10,page{11,12},13"; 

i have following code:

std::vector<std::string> found_list; boost::split(found_list,text,boost::is_any_of(",")) 

but desired output is:

1 2 3 max(4,5,6,7) array[8,9] 10 page{11,12} 13 

regarding parentheses , braces, how implement it?

you want parse grammar.

since tagged boost let me show using boost spirit:

live on coliru

#include <boost/spirit/include/qi.hpp>  namespace qi = boost::spirit::qi;  int main() {     std::string const text="1,2,3,max(4,5,6,7),array[8,9],10,page{11,12},13";      std::vector<std::string> split;      if (qi::parse(text.begin(), text.end(),                 qi::raw [                     qi::int_ | +qi::alnum >> (                         '(' >> *~qi::char_(')') >> ')'                       | '[' >> *~qi::char_(']') >> ']'                       | '{' >> *~qi::char_('}') >> '}'                     )                 ] % ',',                 split))     {         (auto& item : split)             std::cout << item << "\n";     } } 

prints

1 2 3 max(4,5,6,7) array[8,9] 10 page{11,12} 13
