Answer 1

Represents HTML tag attribute. If you need a value of it, you must use its Value property.

For example:

doc.Load(resp.GetResponseStream());
foreach (HtmlNode input in doc.DocumentNode.SelectNodes("//input"))
{
     HtmlAttribute attr = input.Attributes["value"];
     if (attr != null)
        Console.WriteLine(attr.Value);
} 

For HTML:

<input type=text name="myInput" value="Come get some!" />

output will be: Come get some!

EDIT: Null check added
