QWebView Reading content shown by Javascript

[lhg]

I'm developing a WebBrowser that has a single purpose; Access a single website and read the HTML to collect some overall information. The problem is that some of the website's content is displayed by JavaScript, therefore its contents is not in the HTML.
How can I "intercept" a javascript function, and somehow collect its final result? (The content which is displayed to the user)

Thanks,
LuÃ*s.
