That would then be something like this (I didn't try the below code):

    QString Whatever::dbIdentifier(const QString &indexXml) const
    {
        const QFileInfo fileInfo(indexXml);
        return QStringLiteral("%1-%2").arg(
            QString::fromUtf8(QCryptographicHash::hash(
                indexXml.toUtf8(),
                QCryptographicHash::Md5).toHex()).left(8),
            fileInfo.dir().dirName());
    }
