Remove all special characters in a string

Kycho

Hi. I would like to remove all special characters from the string.

This is my code.

            str = str.simplified();
            str = str.remove("!");
            str = str.remove("@");
            str = str.remove("#");
            str = str.remove("$");
            str = str.remove("%");
            str = str.remove("^");
            str = str.remove("&");
            str = str.remove("*");
            str = str.remove("(");
            str = str.remove(")");
            str = str.remove("_");
            str = str.remove("+");
            str = str.remove("-");
            str = str.remove("=");
            str = str.remove(";");
            str = str.remove("'");
            str = str.remove(":");
            str = str.remove('"');
            str = str.remove("'");
            str = str.remove("/");
            str = str.remove(".");
            str = str.remove(",");
            str = str.remove("<");
            str = str.remove(">");
            str = str.remove("?");
            str = str.remove("[");
            str = str.remove("]");
            str = str.remove("{");
            str = str.remove("}");
            str = str.remove(" ");

Of course it works well, but ... Is there more productive code?

Thanks in advance for your advice.

@Kycho use a regular expression and http://doc.qt.io/qt-5/qstring.html#replace-12

Or, if you don't feel like bothering with regular expressions:

auto it = std::remove_if(str.begin(), str.end(), [](const QChar& c){ return !c.isLetterOrNumber();});
str.chop(std::distance(it, str.end()));
