How to write the model data to the XML file ?

If you simply want to write out data you could make use of the QXmlStreamReader class. Just pack your data in blocks line by line.

Edit: of course QXmlStreamWriter*

Thanks for the reply.
I have used QXmlStreamWriter as shown below.
But i had fixed 4 values . Now the value is constantly changing .

    //Open a new XML File
    file =new QFile(filename);
    file->open(QIODevice::WriteOnly);

    xmlWriter =new QXmlStreamWriter(file);
    xmlWriter->setAutoFormatting(true);
    xmlWriter->writeStartDocument();

void XMLWriter::WriteFilterSettings(int filter_values[32][32])
{
    QString var;
    xmlWriter->writeComment("comment");
    xmlWriter->writeStartElement("startelement");

    for (int row = 0; row < 32; ++row)
    {
        xmlWriter->writeStartElement(QString("RT%1").arg(row));
        for (int column = 0; column < 32; ++column)
        {
            if(filter_values[row][column] == 0)
            {
                var ="TR";
            }
            else if(filter_values[row][column] == 1)
            {
                var ="T";
            }
            else if(filter_values[row][column] == 2)
            {
                var ="R";
            }
            else    //Disabled//
            {
                var ="Disabled";
            }
            xmlWriter->writeTextElement(QString("SA%1").arg(column), var);
        }
        xmlWriter->writeEndElement();
    }
    xmlWriter->writeEndElement();
}

The code seems fine, if I understand you correctly, your are now having real values and not having your "var" with fixed strings. Then just put the correct values of your model into the writer:

model->item(row,column)->text();  //If you have text or data(Qt::DisplayRole) or similar

I have set the values previously.

 if(var == "TR")
            {
                filter_values[row][column] = 0;
            }
