QXmlStreamReader to parse HTML String

**francesco_it** · 2012-01-20, 12:06

Hello,

I'm trying to parse a Html page using QXmlStreamReader but Im stuck somewhere...
I use this method to parse the data

Code:

void Person::findIt(QNetworkReply *repToRead)
{


    QByteArray bytes = repToRead->readAll();  // bytes

    QString string(bytes); // string

    QXmlStreamReader xml(string);


    while (!xml.atEnd()) {
        if(xml.readNext()){

            qDebug() << xml.name();

            if(xml.name() == "head"){
                xml.skipCurrentElement();
            }

        }else if(xml.isEndElement()){
            qDebug() << "endElement";
        }

    }

}

I would like to skip the <head> because of META tags.. and go straight to the body..

I'm getting this in console:
""
""
"html"
""
"head"

and nothing else..how can I bypass the header section?
is there another way to parse html strings in Qt?

Solved using:

Code:

    QByteArray bytes = repToRead->readAll();  // bytes

    QWebPage page;
    QWebFrame * frame = page.mainFrame();


    frame->setContent(bytes);

    QWebElement document = frame->documentElement();
    QWebElementCollection elements = document.findAll("div.className");


    foreach(QWebElement e, elements){

        qDebug()<< "e element" << e.toPlainText();
        m_numberChecked = e.toPlainText();
        emit numberChanged();

    }

Hi Francesco,
This problem has been discussed in some other threads here.
The solution you found is actually good and it's the one I prefer the most, but it's makes use of Webkit.

XML parser works only for well formed documents. HTML headers could contain JS scripts or CSS which makes it not XML compliant.
If you want to check where is the problem, you can use http://www.w3schools.com/xml/xml_validator.asp.
QString::remove(QRegExp("<head>.*</head>")) is a way to remove the header tag completely before parsing it.

Thank you for your answer

Im new to Qt and Symbian and I would like to ask you if Webkit it's supported by Symbian^1 or Symbian^3

Ciao Francesco,
Webkit is supported by Qt for Symbian. If you have more questions about Qt Smbian related stuff, feel free to ask in the Qt Symbian section.
