QString: Remove first occurance of regular expression

问题

QString has a method remove that takes a QRegExp. It removes every occurrence of the regular expression.

Is there a way to remove only the first occurrence of the regular expression?

Answer to QString replace only first occurrence doesn't help. See comment from Akiva there.

You can use next code:

QString message = "This is the original text";
QRegExp rx = QRegExp("is|he", Qt::CaseInsensitive);

if (message.contains(rx)){
    message = message.remove(rx.pos(0), rx.cap(0).size());
}

The final message is:

Th is the original text
