Using HTMLAgilityPack and XPath, there are issues obtaining childNodes.

I am trying to parse the following HTML. I need to get the innertext of all links under a h4 tag with the value "Title".

<h4>Title</h4>
    <ul>
         <li>
             <a>One</a>
         </li>
         <li>
             <a>Two</a>
         </li>
         <li>
             <a>Three</a>
         </li>
    </ul>

I can get the h4 element ok using the following code:

var links = document.DocumentNode.SelectNodes("//h4[contains(text(),'Title')]");

The problem comes with trying to get the a nodes. I have tried the following code but none works:

var urls = member.SelectNodes(".//a");

foreach (var url in urls)
{
    Console.WriteLine(url.InnerText);
}
