#include <string>
#include <algorithm>
#include <iostream>
#include <iterator>
/*
 * 
 */
int main(int argc, char** argv) {

  std::string beg("data=\"");
  std::string en("\"");
  std::string s("list c s data=\"vi\" c c s data=\"việt nam\" c c s data=\"việt nam ơi\" list");

  std::string::iterator itBeg = s.begin();
  std::string::iterator itEnd;

  while(s.end() != (itBeg = std::search(itBeg, s.end(), beg.begin(), beg.end()))) {

      itEnd = std::search(itBeg + beg.size(), s.end(), en.begin(), en.end());
      std::string word;
      std::copy(itBeg + beg.size(), itEnd, word.begin());

      std::cout << "Word:" << word.c_str() << std::endl;
      itBeg = itEnd;
  }
  return 0;
}
