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

        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.

              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?

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

                  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("C:/testprojekt/filesXML/cache.xml");
                      //QFile file("C:/testprojekt/filesXML/parts.xml");
                       QFile file("C:/testprojekt/filesXML/simple.xml");
                      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();
                      

                      }@
