c++ parse html,c++ - QT parse html to txt file - Stack Overflow

I think it's always best if you actually attempt at something and post up your code to serve as a starting point. But I'm bored at work so here goes....

Here's some pseudo-ish code:

// To request data from the interwebs.

QNetworkRequest* request = new QNetworkRequest("http://www.asdf.com");

QNetworkAccessManager* networkMgr = new QNetworkAccessManager();

QNetworkReply* reply = networkMgr->get(request);

// Set up signals & slots (Qt4 style)

QObject::connect(reply, SIGNAL(readyRead()), this, SLOT(readyRead()));

QObject::connect(reply, SIGNAL(error(QNetworkReply::NetworkError)), this, SLOT(error(QNetworkReply::NetworkError)));

Later, when you get your payload, you can read the data and feed it into whatever Qt Xml parser you want (QXmlStreamReader and others!):

void HttpTest::readyRead()

{

QNetworkReply* reply = qobject_cast(sender());

if(reply)

{

if(reply->error() == QNetworkReply::NoError)

{

}

else

{

QString html = reply->readAll();

QXmlStreamReader reader(&html);

// Parse your xml stuff - search for your

node.

// ...

}

}

}
