假设有这样一个串，"fsdfsda13124tag=cpp;2343dfdadf" 我现在已经可以提取出 tag=cpp;了。试问如何能提取出 cpp 这部分?
string s = "fsdfsda13124tag=cpp;2343dfdadf";
_test_regex(s, "tag=(.*?);", result);
void _test_regex(string s, string regex, string& result){
std::smatch m;
std::regex e (regex);
std::regex_search (s, m, e);
for (auto x=m.begin();x!=m.end();x++){
result = x->str();
break;
}
}
