[aha_1980]

@sankarapandiyan

So what's your problem now? Did you try @jsulm's suggestion? Do you get another error?

[sankarapandiyan]

@aha_1980 yes same error i got it repeatdly .@jsulm gave the document to read ,now i am doing that.

    QDomDocument document;

QDomElement root = document.createElement("pushbuttn_text");

   QString text1 = ui->pushbutton1->text();
                         
 QDomElement elemTab1 = document.createElement("ss");

    elemTab1.setAttribute(text1);

//elemTab.appendChild( document.createTextNode( text))

          root.appendChild(elemTab1);

and this is my code

@sankarapandiyan

setAttribute should take 2 argument?

[sankarapandiyan]

@Ratzz nop only one it want to take

[sankarapandiyan]

@Ratzz nop only one it want to take

@sankarapandiyan
You want to take one attribute ??
Did you see document ? http://doc.qt.io/archives/qt-4.8/qdomelement.html#setAttribute
What is the error now?

This is wrong.
setAttribute takes two arguments as you can see in documentation.
A XML attribute has a name and a value, that's why setAttribute has two parameters.

[sankarapandiyan]

@jsulm oh sry for my wrong answer
is it possible to do without attribute !coz i want to read one paramtr only

[Ratzz]

@sankarapandiyan

yes but using QDomText
But it creates the text node.

[sankarapandiyan]

@Ratzz by directly reading ??

[jsulm]

@sankarapandiyan I don't understand you: setAttribute sets an attribute, it does not read anything. So, what do you want to do?
If your attribute does not have a value you can pass empty string as value:

elemTab1.setAttribute(text1, "");

@sankarapandiyan

May be this way

    QString text1 = ui->pushbutton1->text();
    QDomText t = doc.createTextNode(text1);
    tag.appendChild(t);

[sankarapandiyan]

@Ratzz i think it will work i will try thanks a lot

@sankarapandiyan

May be this

void MainWindow::on_okbutn_clicked()
{
    QDomDocument document;

    QDomElement root = document.createElement("pushbuttn_text");
    document.appendChild(root);

    QDomElement elemTab1  = document.createElement("ss");
    root.appendChild(elemTab1 );

    QString text1 = ui->pushbutton1->text();
    QDomText t = document.createTextNode(text1);
    elemTab1 .appendChild(t);

    QFile file("C:\\Users\\name\\Desktop\\test.xml");
    if(!file.open(QIODevice::WriteOnly | QIODevice::Text)) {
        qDebug() << "Open the file for writing failed";
    } else {
        QTextStream stream(&file);
        stream << document.toString();
        file.close();
        qDebug() << "Writing is done";
    }
}

@Ratzz yes it works but its repeat for three times i dont know why ! :-(
but anyway thanks all for helping me

[VRonin]

For people passing by, using the entire xml module for operations like these is like using a bazooka to kill a fly.
QXmlStreamWriter is more than enough and it's also probably easier to use

[sankarapandiyan]

@VRonin yeah! i know i will try surely
