Run Javascript code on webbrowser website

Question

What I have is simple, a form with in that form a webbrowser-controll.

That webbrowser goes to a website. And that all works.

But what I wan't to do when he's on the page is to let him run some javascript code (or jQuery if that's possible) to get all the text thats between the tags on the website.

How should I do that?

EDIT: Thanks to Birk, the code now looks like this:

HtmlElementCollection bigFontTags = webBrowser1.Document.GetElementById("Frame_A").Document.GetElementsByTagName("b");
            string[] textPieces = new string[bigFontTags.Count];
            for (int i = 0; i < bigFontTags.Count; i++) {
                textPieces[i] = bigFontTags[i].InnerText;
            }
            //process text
            string bigText = String.Join(" ", textPieces);
            MessageBox.Show(bigText);

But that doesn't work. That is because the element that i need to get, is deep inside frame's and frameset's.... This is the layout (simple):



    
    

        

        
        
And then are here some tables and the content that i want to get.....

So how can i get that content from there??? (in a nice way???)

EDIT2: I will post the generated source of the website: (NOTE! i've deleted everything that wassn't relevant... So only the way from the begin to the content)

                            AND HERE THE CONTENT!!!!

EDIT 3 : Thanks to Birk, the problem is solved, and this is the answer:

HtmlWindow SContentFrame = webBrowser1.Document.Window.Frames[1];
            HtmlWindow Frame_A = SContentFrame.Document.Window.Frames[2];
            HtmlElementCollection bigFontTags = Frame_A.Document.GetElementsByTagName("b");
            string[] textPieces = new string[bigFontTags.Count];
            for (int i = 0; i < bigFontTags.Count; i++) {
            textPieces[i] = bigFontTags[i].InnerText;
            }
            string bigText = String.Join(" ", textPieces);
            MessageBox.Show(bigText);

Create a DocumentCompleted-event and process all tags using ((WebBrowser)sender).Document.GetElementsByTagName("b");.

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            HtmlElementCollection bigFontTags = ((WebBrowser)sender).Document.GetElementsByTagName("b");
            string[] textPieces=new string[bigFontTags.Count];
            for (int i = 0; i < bigFontTags.Count; i++)
            {
                textPieces[i] = bigFontTags[i].InnerText;
            }
            //process text
            string bigText = String.Join(" ", textPieces);
            MessageBox.Show(bigText);
        }

That's not JavaScript, but the result is exactly the same.

EDIT #2: For all those nested frames you could use:

HtmlElementCollection bigFontTags = webBrowser1.Document.GetElementById("SContentFrame").Document.GetElementById("SContentFrame").Document.GetElementById("Frame_A").Document.GetElementsByTagName("b");

That should work, if I understand your frameset structure correctly.
