title: Scrapy getting href out of div
body: <p>I started to use Scrapy for a small project and I fail to extract the link. Instead of the url I get only "[]" for each time the class is found. Am I missing something obvious?</p>
  
  <pre><code>sel = Selector(response)
  for entry in sel.xpath("//div[@class='recipe-description']"):
      print entry.xpath('href').extract()
  </code></pre>
  
  <p>Sample from the website:</p>
  
  <pre><code>&lt;div class="recipe-description"&gt;
      &lt;a href="http://www.url.com/"&gt;
          &lt;h2 class="rows-2"&gt;&lt;span&gt;SomeText&lt;/span&gt;&lt;/h2&gt;
      &lt;/a&gt;
  &lt;/div&gt;
  </code></pre>
