title: Html Agility Pack, SelectNodes from a node
body: <p>Why does this pick all of my <code>&lt;li&gt;</code> elements in my document?</p>
  
  <pre><code>HtmlWeb web = new HtmlWeb();
  HtmlDocument doc = web.Load(url);
  
  var travelList = new List&lt;Page&gt;();
  var liOfTravels = doc.DocumentNode.SelectSingleNode("//div[@id='myTrips']")
                       .SelectNodes("//li");
  </code></pre>
  
  <p>What I want is to get all <code>&lt;li&gt;</code> elements in the <code>&lt;div&gt;</code> with an <code>id</code> of "myTrips".</p>
