Question
I'm attempting to create a simple application that would read text from a Wikipedia page. To get the html, I discovered the following code on another website.
HtmlDocument doc = new HtmlDocument();
StringBuilder output = new StringBuilder();
doc.LoadHtml("http://en.wikipedia.org/wiki/The Metamorphosis of Prime Intellect");
var text = doc.DocumentNode.SelectNodes("//body//text()").Select(node => node.InnerText);
foreach (string line in text)
output.AppendLine(line);
string textOnly = HttpUtility.HtmlDecode(output.ToString());
Console.WriteLine(textOnly);
The following line is highlighted when I get the runtime error "ArgumentNullException was unhandled":
var text = doc.DocumentNode.SelectNodes("//body//text()").Select(node => node.InnerText);
Does anybody recognize the issue?

doc.LoadHtml
takes 6 to zzz not 10 to zzz. You may use to download that pageHtmlAgilityPack.HtmlWeb
class
var web = new HtmlAgilityPack.HtmlWeb();
var doc = web.Load("http://en.wikipedia.org/wiki/The Metamorphosis of Prime Intellect");
var text = doc.DocumentNode.SelectNodes("//body//text()").Select(node => node.InnerText);
var output = String.Join("\n", text);
SelectNodes
In my test, 622 things are returned.
