QXmlStreamReader - Get XML file attributes

Iago.B.Almeida

I'm trying to get the attributes from an XML file using QXmlStreamReader but I can't find the right method to do it, here is my code:

C++

QFile file("file.xml");
    file.open(QFile::ReadWrite);
    QXmlStreamReader reader(&file);
    while(reader.readNextStartElement()){
        while(reader.readNextStartElement()){
            if(reader.name() == "anotation"){
                qDebug() << reader.qualifiedName();     //Returns the tag name
                qDebug() << reader.readElementText();   //Returns the text inside the tag
                //Here i need to get the tag parameters
            }
        }
    }

And here is my file, from where I'm trying to get the values from frame_ini and frame_fin:
XML

<data>
	<anotations>
		<anotation frame_ini = "0" frame_fin = "0"> Anotação teste de frame único </anotation>
		<anotation frame_ini = "10" frame_fin = "14"> Anotação do frame 10 ao 14 </anotation>
		<anotation frame_ini = "15" frame_fin = "15"> Esta aparece apenas no frame 15 </anotation>
		<anotation frame_ini = "20" frame_fin = "30"> Do frame 20 ao 30 existe esta anotação </anotation>
		<anotation frame_ini = "31" frame_fin = "31"> A anotação atual só será exibida no frame 31 </anotation>
	</anotations>
</data>

SOLVED
If anyone is also having this problem, here is the solution:
C++

reader.attributes().value("frame_ini");

Hi,
Thanks for the answer!
I'm reading it right now, but it's really complex. I guess there might be an easier way to get that values.

UPDATE
I've found this method:

reader.attributes().length();

It returns "2", that is the exact number of parameters from the annotations, but when I try to get the values it returns me this error:
C++

qDebug() << reader.attributes().first().value();

This is the line from the code that tries to get the value from the first parameter.

The inferior stopped because it received a signal from the operating system.

Signal name : 
SIGABRT
Signal meaning : 
Aborted

UPDATE:

Got it!
I need to use the qualifiedName from the attribute i want to reach, like this:
C++

reader.attributes().value("frame_ini");
