C++ , Regular expression

I know how to find regular expression in specific string. How to find first element that match with regular expression?

Here is my code:

QString mangledText;
QRegExp rx("string");
while ((pos = rx.indexIn(mangledText)) != -1){
 mangledText.replace(pos, rx.matchedLength(), "replaced string");      
}

I want to replace first match result (or second or third) instead of all of that.

Any suggestion?

Use an if instead of a while.

if ((pos = rx.indexIn(mangledText)) != -1){
   mangledText.replace(pos, rx.matchedLength(), "replaced string");    
}
