[OK] - QWebView - Getting source html or xml

maximus

I am trying to retrieve the source html/xml of a QWebView.

When I use QDebug() on it, it always show me an empty QString.
However, I can see content in the QWebView, so i'm missing something

Here is the QWebView (#2 on the right) with text inside it (xml)
https://www.dropbox.com/s/za8kv9ionowb5lc/readQWebViewSource.png

Here is my code that try to read the source of the QWebView :
@void DialogLogin::loginWebViewUrlChanged(){

qDebug() << "URL_CHANGED:" << ui->webView_login->url();

if (ui->webView_login->url().toDisplayString().contains("current_account_cookie"))
{
    qDebug() << "GOT IN!, PARSE XML";
    qDebug() << ui->webView_login->page()->currentFrame()->url();
    qDebug() << ui->webView_login->page()->currentFrame()->toHtml();
    qDebug() << ui->webView_login->page()->currentFrame()->toPlainText();
    qDebug() << ui->webView_login->page()->currentFrame()->documentElement().toPlainText();
    qDebug() << ui->webView_login->page()->currentFrame()->documentElement().toOuterXml();

    //        loginAccepted();
}

}@

log :
@URL_CHANGED: QUrl( "http://localhost/index.php/api/account_rest/current_account_cookie" )
GOT IN!, PARSE XML
QUrl( "http://localhost/index.php/api/account_rest/current_account_cookie" )
""
""
""
"" @

If you have any idea why it's printing "" instead of the current content, i'd appreciate some help, thanks!

I can now get the xml node name, but can't access the value inside it so far.

<last_activity>1405096946</last_activity>
I can only retrieve the node "last_activity" but not the value.. still looking

@void DialogLogin::loginLoaded(){

qDebug() << "Login loaded!";
ui->webView_login->setFocus();

if (ui->webView_login->url().toDisplayString().contains("current_account_cookie"))
{
    qDebug() << "GOT IN!, PARSE XML";

    QWebFrame *frame = ui->webView_login->page()->mainFrame();
    QWebElement document = frame->documentElement();

    QWebElement element = document.firstChild();
    while (!element.isNull())
    {
        qDebug() << element.tagName();
      /// no element.value()?
        qDebug() << element.firstChild().toPlainText();
        element = element.nextSibling();
    }
}

}@

log :
@
"session_mt_id"
""
""
"session_mt_expire"

"last_mt_activity"

Still looking for a reliable way to parse a XML document from a QwebView page:

I know the Xml is well formed, inside a browser I get this :
https://www.dropbox.com/s/e5h88hxmkhmeey9/restXml.png

inside a QWebView I get this:
https://www.dropbox.com/s/26ij4xf36z8j4e4/insideQWebView.png

I currently only get the node name and not the value inside Using this code :
@ QWebFrame *frame = ui->webView_login->page()->mainFrame();
QWebElement document = frame->documentElement();

    QWebElement element = document.firstChild();
    while (!element.isNull())
    {
        qDebug() << element.tagName(); /// this get the node name good
        /// how to get the element value ?
        qDebug() << element.firstChild().toPlainText();
        element = element.nextSibling();
    }@

Thanks

I have decided to use a QNetworkReply and use readyRead() on it instead of sending it to the QWebView. this way I can parse Xml using qxmlstreamreader
