title: Hpple with complex HTML in iOS
body: <p>How I can parse complex html with many child tags with hpple in iOS. I cant find any good and complex tutorial or any good documentation about this library. with simple parsing there is no any problem. the html example is:</p>
  
  <pre><code>&lt;div class="post shortcuts_item focus" id="post_243273"&gt;
  &lt;div class="published"&gt;today in 21:03&lt;/div&gt;
  &lt;h1 class="title"&gt;
      &lt;a href="http://example.ru/post/243273/" class="post_title"&gt;Some simple title text here&lt;/a&gt;
  &lt;/h1&gt;
  
  &lt;div class="hubs"&gt;
      &lt;a href="http://example.ru/hub/internet_regulation/" class="hub"&gt;Simple text 1&lt;/a&gt;&lt;span class="profiled_hub" title="Profile 1"&gt;*&lt;/span&gt;, 
      &lt;a href="http://example.ru/hub/business-laws/" class="hub"&gt;Simple text 2&lt;/a&gt;&lt;span class="profiled_hub" title="Profile 2"&gt;*&lt;/span&gt;, 
      &lt;a href="http://example.ru/hub/vkontakte/" class="hub"&gt;Simple text 3&lt;/a&gt;&lt;span class="profiled_hub" title="Profile 3"&gt;*&lt;/span&gt;, 
      &lt;a href="http://example.ru/hub/social_networks/" class="hub"&gt;Simple text 4&lt;/a&gt;&lt;span class="profiled_hub" title="Profile 4"&gt;*&lt;/span&gt;, 
      &lt;a href="http://example.ru/hub/facebook/" class="hub"&gt;Simple text 5&lt;/a&gt;&lt;span class="profiled_hub" title="Profile 5"&gt;*&lt;/span&gt;
  &lt;/div&gt;
  &lt;div class="content html_format"&gt;
      &lt;img src="//example.org/files/aa9/f6c/8a0/aa9f6c8a049e405c9f72bf10ee3a2e9f.png"&gt;&lt;br&gt;
      &lt;br&gt;
      Simple but very long text with link tag  &lt;a href="http://example.ru/post/243273/#blahblah"&gt;Simple link...&lt;/a&gt;
      &lt;div class="buttons"&gt;
          &lt;a href="http://example.ru/post/243273/#habracut"&gt;Read more...&lt;/a&gt;
      &lt;/div&gt;
      &lt;div class="clear"&gt;&lt;/div&gt;   
  &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>The question is how to get all <code>A</code> tags inside the <code>class="hubs"</code> with one run. How I can do that?</p>
