Error when try to load html with htmlagiltypack

I am trying to run this code

string path = "http://warisons.rssing.com/chan1729325/all_p43.html";
HtmlAgilityPack.HtmlDocument htmlDoc = new HtmlAgilityPack.HtmlDocument();
htmlDoc.LoadHtml(path);
var div = htmlDoc.DocumentNode.Descendants("div");
foreach (var x in div)
{
    Console.WriteLine(x.Attributes["class"].Value);
}

when I debug this code in htmlDoc.LoadHtml(path); I got this error

Your attempt to load html document from URI is incorrect.

Methof HtmlDocument.LoadHtml loads html from string provided, so its argument is html text itself, not URI.

To load html from provided URI you need something like:

string path = "http://warisons.rssing.com/chan1729325/all_p43.html";
HtmlAgilityPack.HtmlDocument htmlDoc = new HtmlWeb().Load(path);

Also note you can get NullReferenceException here:

x.Attributes["class"].Value

since you're not checking if there is class attribute (x.Attributes["class"] != null) before accessing its value.
