如何在Webkit.Net中选择用户控件WebKitBrowser的所有文本？

Question

There is a method SelectedText in WebKitBrowser, however, no SelectAll . Is there a way for me to do something like the following:

string GetAllTextOfBrowserAsPlainText(WebKitBrowser webKitBrowser)
{
    webKitBrowser.SelectAll(); //Doesn't exist
    return webKitBrowser.SelectedText;
}

My goal is to render a webpage entirely (including styling) and then copy the content of a webpage in plane text as if I used copy/paste in my browser.

Getting the InnerText or working with the HTML directly is not an option.

I have tried the WebBrowser UC with WebBrowser1.Document.ExecCommand to capture the text however I couldn't get the styling to work properly. I am now trying WebKit, and I am so close to getting what I want. Any help? Does ExecCommand("SelectAll",...) exist for WebKit?

Answer 1

Try using WebClient

       using (WebClient wc = new WebClient())
      string mystring= wc.DownloadString("http://yoururl.com");

Answer 2

I solved the problem by adding javascript to the end of the downloaded html. Calling js from code was tricky, since it seems like WebKit.Net has trouble with doing this directly. The following is not my final production code, but will help anybody in the same spot along the way:

private WebKitBrowser _browser = ...;
private string _selectAllCopyScript = "<script>document.execCommand('SelectAll', false, null);document.execCommand('Copy', false, null); </script>";
private string _plain = ...;

Form1()
{
    ...
    _browser.DocumentCompleted += OnDocumentCompleted;
}

private string GetAllTextOfBrowserAsPlainText(String html)
{
    _browser.Focus();
    _browser.DocumentText = html + _selectAllCopyScript; //Calls OnDocumentCompleted when done
}

private void OnDocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    _plain = Clipboard.GetText();
    Clipboard.Clear();
}

I wish I found a solution which didn't have to use the clipboard. The final plain text copied html is stored in _plain .
