    Default QWebView Extract Information

    I have a QWebView that loads a page that has some javascript which modifies the document on the fly. AKA:
    Qt Code:
    1. document.getElementByID("displayWindow").innerHTML = "Somegeneratedtext";
    To copy to clipboard, switch view to plain text mode 
    Is there a way to for my Qt program to look at the modified page, and capture this changed text in say, a QString, perhaps like QTextCursor?

    Default Re: QWebView Extract Information

    From what it looks like, I could use QWebPage * page () to get the page, then QWebFrame * currentFrame () to get the singular frame that appears.

    From there I can use QVariant evaluateJavaScript ( const QString & scriptSource ) to "inject" a script that will check the innerhtml, or i could use toHtml () or toPlainText () and parse out the pieces of the web page that I was interested in.

    Does this sound like the right direction to go? or is there an easier way?

    For now there is no direct access to page's DOM tree, so you have to use JavaScript.
