Format XML file

[vikuseth]

void format(void)
{
    QDomDocument input;
 
    QFile inFile("D:/input.xml");
    QFile outFile("D:/output.xml");
 
    inFile.open(inFile.Text | inFile.ReadOnly);
    outFile.open(outFile.Text | outFile.WriteOnly);
 
    input.setContent(&inFile);
 
    QDomDocument output(input);
    QTextStream stream(&outFile);
    output.save(stream, 2);
}

void format(void)
{
    QDomDocument input;

    QFile inFile("D:/input.xml");
    QFile outFile("D:/output.xml");

    inFile.open(inFile.Text | inFile.ReadOnly);
    outFile.open(outFile.Text | outFile.WriteOnly);

    input.setContent(&inFile);

    QDomDocument output(input);
    QTextStream stream(&outFile);
    output.save(stream, 2);
}

To copy to clipboard, switch view to plain text mode 

What i have to do if i have to save the contents inside the same file . like in the above case for D:/input.xml .

Write the output to a temporary file and, when that is successfully closed rename it to replace the original.
Or, write the result to a buffer in memory and when that is complete write the buffer to the file.
