title: can't get proper information from amazon.com using c#/htmlagilitpack
body: <p>I want to get book information such as author name / pages / publish year / etc ...
  from amazon using HtmlAgilityPack but seems amazon webpages have some problems and I can't access the appropriate fields.</p>
  
  <p>here is what I've done  :</p>
  
  <p>I use Firefox and Firebug + FirePath to retrieve desired XPath and then inside my code I summon HtmlAgilityPack and instruct it to get information using acquired XPath that I've got it from Firebug
  but no luck and till now I couldn't access the "Product Details" part of the amazon.com</p>
  
  <p>and this is my XPath (which is working only with HtmlAgilityPack)</p>
  
  <pre><code>HtmlAgilityPack.HtmlNodeCollection cnt = doc.DocumentNode.SelectNodes("//*[@class='content']");
  int i=1;
  foreach (HtmlAgilityPack.HtmlNode content in cnt)
  {
      if (i != 3)
      {
          i++;
          continue;
      }
      if (i == 3) // i==3 means I've reached the product details but I can't go any further :(
      {
  
          s = content.SelectSingleNode("").OuterHtml;
  
        //  break;
      }
  
  }
  </code></pre>
  
  <p>How can I access <strong>Product Details</strong> using appropriate understandable XPath for HtmlAgilityPack?</p>
  
  <p>And why does the syntax of Firebug + FirePath XPath is different from HtmlAgilityPack?</p>
