Using QString I can remove any character from string, but what would be QRegExp to remove ALL non alphanumeric characters from that string. Currently I have written a function that will remove each character one by one, but I would like to know if i can do the same thing only in one step.

Here is my function

Qt Code: 
  1. QString clean(QString str)
  2. {
  3.     str.remove("\"");
  4.     str.remove("\\");
  5.     str.remove(".");
  6.     str.remove(",");
  7.     str.remove("?");
  8.     str.remove("!");
  9.     str.remove("'");
  10.     str.remove("`");
  11.     str.remove("-");
  12.     str.remove("_");
  13.     str.remove("—");
  14.     str.remove("@");
  15.     str.remove("#");
  16.     str.remove("$");
  17.     str.remove("%");
  18.     str.remove("^");
  19.     str.remove("&");
  20.     str.remove("*");
  21.     str.remove("(");
  22.     str.remove(")");
  23.     str.remove("{");
  24.     str.remove("}");
  25.     str.remove("[");
  26.     str.remove("]");
  27.     str.remove("|");
  28.     str.remove(";");
  29.     str.remove(":");
  30.     str.remove("/");
  31.     str.remove(">");
  32.     str.remove("<");
  33.     str.remove("~");
  34.     str.remove("=");
  35.     str.remove("+");
  36.     str.remove(str.fromUtf8("«"));
  37.     str.remove(str.fromUtf8("»"));
  38.     str = str.trimmed();
  39.     return str;
  40. }
