Search for QRegExp in a QString

I have a tabbed interface in my application. I am getting the contents of the focused tab in a string variable as
QString myString = currentTab->getTextEdit()->toPlainText();

Now, I want to search this string for the occurrence of some other strings which I have defined as a regular expression and for each occurrence, I want to prepend a character to the occurrence. Please let me know how to find every occurrence of regular expression in myString.

See QString::indexOf().

Using indexOf() I am able to prepend the required character only to the first occurrence of the RegExp in myString. How can I do the same for all the occurrences??

Invoke indexOf() once more, but this time use the second parameter and return value to skip the previous occurence.

This does not work if there are multiple occurrences of the same RegExp and it is not even known how amny times a particular RegExp would occur. How can I find multiple occurrences and make the required change??

did you see this example?

Code:

QRegExp rx("(\\d+)");
QString str = "Offsets: 12 14 99 231 7";
QStringList list;
int pos = 0;
 
while ((pos = rx.indexIn(str, pos)) != -1) {
    list << rx.cap(1);
    pos += rx.matchedLength();
}
