New Post: Extract href by anchor text?

I see that this was never answer, but just in case someone else is looking for answer, here is one way of doing it:

var htmlDoc = new HtmlDocument();
htmlDoc.LoadHtml({yourHtmlContentOrFile});
var rootNode = htmlDoc.DocumentNode;
var refs = rootNode.SelectNodes("//*/a/@href");
var link =refs.ElementAt(0).Attributes["href"].Value;
