It’s quite convenient to iterate with std::regex_iterator and std::regex_token_iterator over the matched texts. std::regex_iterator matched texts and their capture groups. std::regex_token_iterator supports more. We can address the components of each capture and by using a negative index, we can access the text between the matches.
