The following code worked for me

public static string GetComments(string html)
{
    HtmlDocument doc = new HtmlDocument();
    doc.LoadHtml(html);
    string s = "";
    foreach (HtmlNode node in doc.DocumentNode.SelectNodes("//ol"))
    {
        s += node.OuterHtml;
    }

    return s;
}

How about:

var el = (HtmlElement)doc.DocumentNode
    .SelectSingleNode("//ol");
if(el!=null)
{
    string s = el.OuterHtml;
}

(untested, from memory)
