c++ - boost::split 返回 sep 字符

Question

我正在使用boost::split(lines, str, boost::is_any_of(delims));现在我想知道在每个拆分中找到了哪个 delim 字符。我会把那个字符放在分割线的末尾。这样我就可以重新创建原始字符串。我已经搜索但在boost::split我需要使用任何其他功能吗？

mbboost::tokenizer与boost::char_separator？

http://www.boost.org/doc/libs/1_51_0/libs/tokenizer/char_separator.htm

例子。

#include <iostream>
#include <string>
#include <boost/tokenizer.hpp>

int main()
{
   std::string str = "hello, and what do. you? want";
   typedef boost::tokenizer<boost::char_separator<char> > tokenizer;
   boost::char_separator<char> sep("", " ,.?");
   tokenizer tokens(str, sep);
   for (tokenizer::iterator pos = tokens.begin(); pos != tokens.end(); ++pos)
   {
      std::cout << *pos << std::endl;
   }
}
