Parsing HTML page with HtmlAgilityPack

Question

Using C# I would like to know how to get the Textbox value (i.e: john) from this sample html script :

Answer 1

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(html);
XPathNavigator docNav = doc.CreateNavigator();

XPathNavigator node = docNav.SelectSingleNode("//td/input/@value");

if (node != null)
{
    Console.WriteLine("result: " + node.Value);
}

I wrote this pretty quickly, so you'll want to do some testing with more data.

NOTE: The XPath strings apparently have to be in lower-case.

EDIT: Apparently the beta now supports Linq to Objects directly, so there's probably no need for the converter.
