[Solved]XML readproblems

Look at this: it seems that your input is not complete when you are trying to parse the XML document.

Thanks
I'll Try this tomorrow.

I thought this would be enough
@QXmlStreamReader s(&in);@

JohanSolo

Well, it depends what is you in object. If it's a file on disk, I agree with you. However if you're downloading the file for instance with QNetworkAccessManager / QNetworkReply, you better wait till the file is completely downloaded and written.

I'm pretty sure there's an example of this somewhere...

Edit : found what I wanted, when I was trying to do such a thing this thread and this one as well helped me.

I got the file in the same folder as the application on the disk but I will try with another xml file

This is the problem

@s.readElementText();@
anyone
pls

JohanSolo

The readElementText() method uses readElementText( ErrorOnUnexpectedElement ).
As far as I understand this error means that your file (assuming the reading of the full file is OK) doesn't contain valid XML: it tries to find the corresponding EndElement till the end of the file but cannot...

Why don't you start trying to read a simple xml, like this one?

toho71

I did that with a simple xml file and I tried your exampel to but same error.
This is a big problem now.

JohanSolo

It means that you're using the readElementText in a wrong way... I'm afraid I cannot help you much more than I already tried. I'm not a big QXmlStreamReader user.

thank you for your help.
Is it easier to use sax or dom to get the values in the xml

Got it to work

@void MainWindow::init()
{

//QFile file&#40;"C:/testprojekt/filesXML/cache.xml"&#41;;
//QFile file&#40;"C:/testprojekt/filesXML/parts.xml"&#41;;
 QFile file&#40;"C:/testprojekt/filesXML/simple.xml"&#41;;
if (file.exists())
    qDebug() << file.fileName();
else
    qDebug() << "NO " + file.fileName();

file.open(QIODevice::ReadOnly);

    QXmlStreamReader xml_stream(&file);
    while (!xml_stream.atEnd() && !xml_stream.hasError())
    {
        if (xml_stream.isStartElement() && xml_stream.name() =="description")

             ui->textBrowser->append( + "<" + xml_stream.name().toString()
                                     + ">" + xml_stream.readElementText());

        xml_stream.readNext();
    }

 ui->textBrowser->append("-------------------------");


 xml_stream.clear();
 file.close();
