Using QWebElement.findAll() without using QWebFrame and its parent classes

[ntXn]

Hello all,

I wonder if there is any alternative to using QWebElement.findAll() without setting up classes up to QWebPage ? Because in my case this causes immense resource consumption from 7MB up to 21MB (also WebCoreNode leak warning) just to create a virtual webpage of nonvisible html code - but I have to admit I did only page.deleteLater(); to manage resources. Here is the code:
Reply is QNetworkReply

QWebPage page;
QWebFrame *frame = page.mainFrame();
QString htmlReply = Reply->readAll();
frame->setHtml(htmlReply);
QWebElement html = frame->documentElement();
QWebElementCollection myOutput = html.findAll("DIV.myClass");

QWebPage page;
QWebFrame *frame = page.mainFrame();
QString htmlReply = Reply->readAll();
frame->setHtml(htmlReply);
QWebElement html = frame->documentElement();
QWebElementCollection myOutput = html.findAll("DIV.myClass");

To copy to clipboard, switch view to plain text mode 

Or do I have to use regexp search on qstring with html code?

Thanks for any answers
