Is it possible to use QString::contains(QRegExp) in a switch statement?

[MarekR22]

Can you be more specific what you are parsing?
I'm quite sure that this issue can be solved in better way.
One of possibilities is union of regular expretions:

QRegExp regExp("(regExp1)|(regExp2)|(regExp3)|(regExp4)")
 
while(1) // this (!in.EOF) was wrong!
{
    line = in.readLine();
    if (line.isNull()) {
         break;
    }
    if(line.contains(regExp)){
        const QStringList result = regExp.capturedTexts();
        int i;
        for (i=0; i<result.count(); ++i) {
             if (!result[i].isEmpty()) {
                   break; // or some action to take
             }
        }
        // process i value
    }
}

QRegExp regExp("(regExp1)|(regExp2)|(regExp3)|(regExp4)")

while(1) // this (!in.EOF) was wrong!
{
    line = in.readLine();
    if (line.isNull()) {
         break;
    }
    if(line.contains(regExp)){
        const QStringList result = regExp.capturedTexts();
        int i;
        for (i=0; i<result.count(); ++i) {
             if (!result[i].isEmpty()) {
                   break; // or some action to take
             }
        }
        // process i value
    }
}
