So I have a website which I load into my form's webbrowser control. After loading the document, I retrive the webbrowser.documenttext . I am looking here to parse specific table. But I am not finding the table in here but I see that it is being dispayed in the form browser.

I tell you that this specific table is being loaded/appended to doc by already loaded javascript code. When I right click and select the "View Source" , it pops the document with correct html.

My question is how can I get the same document referenced by ViewSource or is there any way to get the document what is being rendered on form?

Instead of using Webbrowser Control use HtmlAgilityPackage to parse data based on your need.

 var html = new HtmlDocument();
html.LoadHtml(new WebClient().DownloadString("http://www.asp.net")); 
var root = html.DocumentNode;
var commonPosts = root.Descendants().Where(n => n.GetAttributeValue("class", 
"").Equals("common-post"));

  • But ths will just parse the raw HTML, how about dynamic HTML which has injected scripts and the scripts are making dom changes. I need the latest changed dom. – Mukesh Miraculous Mar 10 '19 at 07:32

The above issue was very similar to my issue and after going thorough the answer I learnt that I somehow need to wait and poll the webbrowser to get the dynamic content.

I did not really implement the code provided in the answer but I changed my documentCompleted event as async and provided a await task delay of 5s

private async void Browser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    {
        await Task.Delay(5000);
        var html= wb.Document.GetElementsByTagName("HTML")[0].OuterHtml;
    }

Now I get the dynamic result. Thanks, I am feeling now.
