QXmlStreamReader help?

[nthung]

This is a XML file. I want to use QXmlStreamReader to read the value of href, but I don't how to know to get the its value

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xbel>
<xbel version="1.0">
    <folder folded="no">
        <FullName>Perter</FullName>
        <Age>38</Age>
    </folder>
    <bookmark href="http://qt.nokia.com/"/>
</xbel>

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xbel>
<xbel version="1.0">
    <folder folded="no">
        <FullName>Perter</FullName>
        <Age>38</Age>
    </folder>
    <bookmark href="http://qt.nokia.com/"/>
</xbel>

The XML file is produced by this code after modifing the code

But my current problem is update the value of href ="http://qt.nokia.com/" to href="http://www.qtcentre.org/"

Load the document into a QDomDocument, find and modify any elements you want to, then save() the QDomDocument to a QTextStream (file).

THis is code for updating

QFile inFile("C:\\test.xml" );
      inFile.open( QIODevice::ReadWrite | QIODevice::Text );
      QDomDocument document;
      document.setContent( &inFile ) ;
 
 
      QDomElement documentElement = document.documentElement();
        QDomNodeList elements = documentElement.elementsByTagName( "TextWatermark" );
        QDomElement bar = elements.at(0).toElement();
 
        if(bar.hasAttribute("FontName"))
            bar.setAttribute("FontName","Thanh Hung");
 
        QFile outFile( "C:\\test.xml" );
          if( !outFile.open( QIODevice::WriteOnly | QIODevice::Text ) )
          {
            qDebug( "Failed to open file for writing." );
            //return 0;
          }
 
          QTextStream stream( &outFile );
          stream << document.toString();
 
          outFile.close();

QFile inFile("C:\\test.xml" );
      inFile.open( QIODevice::ReadWrite | QIODevice::Text );
      QDomDocument document;
      document.setContent( &inFile ) ;


      QDomElement documentElement = document.documentElement();
        QDomNodeList elements = documentElement.elementsByTagName( "TextWatermark" );
        QDomElement bar = elements.at(0).toElement();

        if(bar.hasAttribute("FontName"))
            bar.setAttribute("FontName","Thanh Hung");

        QFile outFile( "C:\\test.xml" );
          if( !outFile.open( QIODevice::WriteOnly | QIODevice::Text ) )
          {
            qDebug( "Failed to open file for writing." );
            //return 0;
          }

          QTextStream stream( &outFile );
          stream << document.toString();

          outFile.close();
