    QXmlStreamWriter stream(&file);
    stream.setAutoFormatting(true);

What is the parent widget on which u have all label and combobox?

[sankarapandiyan]

@Ratzz
Labels and combo boxes are all in tab widget
this is my code,

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
}

MainWindow::~MainWindow()
{
delete ui;
}

void MainWindow::on_pushButton_clicked()
{
{
QFile file("/home/newuser/Desktop/testt.xml");
if (!file.open(QIODevice::WriteOnly | QIODevice::Text))
return;

    QXmlStreamWriter stream(&file);
    stream.setAutoFormatting(true);
    stream.writeStartDocument();
    stream.writeStartElement("country");
    stream.writeAttribute("",ui->comboBox_COUNTRY->currentText());
    stream.writeEndElement();

    stream.writeStartElement("language");
    stream.writeAttribute("",ui->comboBox_LANGUAGE->currentText());
    stream.writeEndElement();

    file.close();
}

}

There are other label and comboboxes apart from the one you want to be write on that tabwidget?

Can you show your tab widget?

[sankarapandiyan]

yes all are in the tab widget @Ratzz

I have tested for 2 combination of label and combobox.

    QXmlStreamWriter stream(&file);
    stream.setAutoFormatting(true);
    stream.writeStartDocument();

    QWidget* pWidget=  ui->mwtabwidget->widget(yourTabIndex);
    QList<QLabel *> labelList = pWidget->findChildren<QLabel *>();
    QStringList comboList ={ ui->comboBox_COUNTRY->currentText(), 
                             ui->comboBox_LANGUAGE->currentText()} ;

    for (int cc = 0; cc < labelList.count(); ++cc)
    {
        stream.writeStartElement(labelList.at(cc)->text());
        stream.writeAttribute("",comboList.at(cc));
        stream.writeEndElement();
    }
    file.close();

Your combox index should be in same order of label. Someone else may have better solution.
