Xml parsing using QXmlStreamReader

[Thom0801]

Hello,

I'm trying to parse an xml file using QXmlStreamReader.

Here my xml file (in my project directory:

<?xml version="1.0" encoding="UTF-8"?>
<!--example with no DTD-->
<root>
    <childA>text1</childA>
    <childA>text2</childA>
    <childB>text3</childB>
    <childA>text4</childA>
</root>

And here an example code :

QFile file("param.xml");
if(!file.open(QFile::ReadOnly | QFile::Text)){
  qDebug() << "Cannot read file" << file.errorString();
}

QXmlStreamReader reader(&file);

if (reader.readNextStartElement()) {
  if (reader.name() == "root"){
      while(reader.readNextStartElement()){
          if(reader.name() == "childA"){
              QString s = reader.readElementText();
              qDebug(qPrintable(s));
          }
          else
              reader.skipCurrentElement();
      }
  }
  else
      reader.raiseError(QObject::tr("Incorrect file"));
}
else{
    if(reader.hasError()) qDebug()<< reader.errorString();
}

execution return error:

"Premature end of document."

Encoding is verified.
Another strange thing occure when i'm trying to use another xml file with the same content on my project directory (test.xml) .
Just change the line :

QFile file("test.xml");

In this case my prog refuse to open the file :

Cannot read file "No such file or directory"
QIODevice::read (QFile, "test.xml"): device not open
"Premature end of document."

Both files are included on my project, are encoded UTF-8, have the same content... juste not the same name....

Any ideas?

Hi and welcome to devnet,

Your path to test.xml is relative so the file should be beside your executable. Currently your executable is located in a shadow build dir. So for your test you can use an absolute path or copy the file in the shadow build dir.
