title: simplehtmldom get href of a title
body: <p>I have a code below which is working correctly but is missing one thing. It is not returning the value for the <code>$item['link']</code> which is the <code>href</code> of the title.</p>
  
  <pre><code>include('simple_html_dom.php');
  $html = file_get_html('http://news.google.com/news/section?pz=1&amp;cf=all&amp;ned=us&amp;q=newzealand'); 
  
  
  foreach($html-&gt;find('.blended-wrapper') as $article) {
      $item['title']     = $article-&gt;find('span.titletext', 0)-&gt;plaintext;
      $item['source']    = $article-&gt;find('span.esc-lead-article-source', 0)-&gt;plaintext;
      $item['clip'] = $article-&gt;find('div.esc-lead-snippet-wrapper', 0)-&gt;plaintext;
  
      $item['link'] = $article-&gt;find('.esc-lead-article-title a')-&gt;href;
  
      $articles[] = $item;
  }
  
  echo "&lt;pre&gt;";
  print_r($articles);
  echo "&lt;pre/&gt;";
  </code></pre>
  
  <p>This is what it outputs, as you see the link key is empty. I've tried so many things.
