Sure:

    QString str(tr("This is a line of text that is a line of text that is a
line of text."));
    QString rpl(tr("bunch of"));
    QRegExp exp("line of");

    int pos = 0;
    while((pos = exp.indexIn(str, pos)) != -1)
    {
        str = str.left(pos) + rpl + str.right(str.length() - (pos +
exp.matchedLength()));
        pos += rpl.length();
    }
