Question

I’m using HtmlAgilityPack and I’d like to select the value from inside the td with class title. I need the value Battlefield 3 which is inside the <a> tag.

I’ve tried the following, just to get the correct td element, and I get an exception object is not set to an instance.

var title = from item in document.DocumentNode.Descendants()
            where item.Name == "td" && item.Attributes["class"].Value == "title"
            select item.InnerHtml;

With this small example, I’ll probably figure out the rest of what I need.

Thank you for the suggestions.

<tr class="first-in-year">
  <td class="year">2011</td>

  <td class="img"><a href="/battlefield-3/61-27006/"><img src=
  "http://media.giantbomb.com/uploads/6/63038/1700748-bf3_thumb.jpg" alt=""></a></td>

  <td class="title">
    <a href="/battlefield-3/61-27006/">Battlefield 3</a>

    <p class="deck">Battlefield 3 is DICE's next installment in the franchise and
    will be on PC, PS3 and Xbox 360. The game will feature jets, prone, a
    single-player and co-op campaign, and 64-player multiplayer (on PC). It's due out
    in Fall of 2011.</p>

Try using XPath selectors with class or other attribute specifiers.

//td[@class='title']/a

It should give you all elements within elements that have the class ‘title’. You would then iterate through that NodeCollection and call the node.InnerText property.

  var nodes = doc.DocumentNode.SelectNodes("//td[@class='title']/a");
  foreach(HtmlNode node in nodes)
  {
     string title = node.InnerText;
  }

The tutorial/resource at W3Schools is pretty good for quick ramp up.
