Creating new XML file

[Pembar]

Hey guys, I have the following code:

void xmlBaseTest::myBlankFile()
{
    QFile data("booklist.xml");
    QDomElement root = doc->createElement("booklist");
    doc->appendChild(root);
 
    if (data.open(QFile::WriteOnly | QFile::Truncate)) {
     QTextStream out(&data);
     doc->save(out,4);
    }
}

void xmlBaseTest::myBlankFile()
{
    QFile data("booklist.xml");
    QDomElement root = doc->createElement("booklist");
    doc->appendChild(root);

    if (data.open(QFile::WriteOnly | QFile::Truncate)) {
     QTextStream out(&data);
     doc->save(out,4);
    }
}

To copy to clipboard, switch view to plain text mode 

It creates the file:

<!DOCTYPE serverlist>
<booklist/>

<!DOCTYPE serverlist>
<booklist/>

To copy to clipboard, switch view to plain text mode 

The line <booklist/> is causing problems, when trying to read it later using .setContent. I was wondering if there was any way to get it to print out <booklist></booklist> instead?

Thanks much

It can't be causing problems, it's perfectly valid. What exactly are the "problems"?

I have an other question about "valid XML":
is it possible to create a header line
<?xml version=\"1.0\" encoding=\"iso8859-1\" ?>"
by some calls of whatever or do I have to set them with

DomDocumentType doctype = impl.createDocumentType("name", QString::null, QString::null);
QDomDocument doc = impl.createDocument("uri", "name", doctype); 
doc.setContent(QString("<?xml version=\"1.0\" encoding=\"iso8859-1\" ?>"));

DomDocumentType doctype = impl.createDocumentType("name", QString::null, QString::null);
QDomDocument doc = impl.createDocument("uri", "name", doctype); 
doc.setContent(QString("<?xml version=\"1.0\" encoding=\"iso8859-1\" ?>"));

Sorry, this piece of code is from Qt3. Until now I did not face the differences of XML code in Qt4.

<?xml version=\"1.0\" encoding=\"iso8859-1\" ?>"

QDomDocument doc("RootElement");
QDomProcessingInstruction process = doc.createProcessingInstruction("xml", "version=\"1.0\" encoding=\"iso8859-1\"");
doc.appendChild(process);

QDomDocument doc("RootElement");
QDomProcessingInstruction process = doc.createProcessingInstruction("xml", "version=\"1.0\" encoding=\"iso8859-1\"");
doc.appendChild(process);
