title: Selecting attribute values with html Agility Pack
body: <p>I'm trying to retrieve a specific image from a html document, using html agility pack and this xpath:</p>
  
  <pre><code>//div[@id='topslot']/a/img/@src
  </code></pre>
  
  <p>As far as I can see, it finds the src-attribute, but it returns the img-tag. Why is that?</p>
  
  <p>I would expect the InnerHtml/InnerText or something to be set, but both are empty strings. OuterHtml is set to the complete img-tag.</p>
  
  <p>Are there any documentation for Html Agility Pack?</p>
