title: Parse HTML iFrame SRC in PHP with SimpleHTMLDOM
body: <p>This how my HTML looks like :</p>
  
  <pre><code>&lt;div class="academy_page"&gt;
      &lt;span class="academy_page_header"&gt;Academy:&lt;/span&gt;
      &lt;div&gt;
          &lt;div class="videopage_block" align="center"&gt;
              &lt;iframe class="videopage_video" src="//player.vimeo.com/video/67353453644?title=0&amp;amp;byline=0&amp;amp;portrait=0" width="300" height="150" frameborder="0" allowfullscreen="allowfullscreen"&gt;&lt;/iframe&gt;
              &lt;div class="academy_text"&gt;How to Ride a Skateboard&lt;/div&gt;
          &lt;/div&gt;
          &lt;div class="videopage_block" align="center"&gt;
              &lt;iframe class="videopage_video" src="//player.vimeo.com/video/9435345343?title=0&amp;amp;byline=0&amp;amp;portrait=0" width="300" height="150" frameborder="0" allowfullscreen="allowfullscreen"&gt;&lt;/iframe&gt;
              &lt;div class="academy_text"&gt;How to Build a Skateboard&lt;/div&gt;
          &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>This is how I'm parsing it:</p>
  
  <pre><code>foreach($html-&gt;find('div.academy_page') as $element){
  
          foreach($element-&gt;find('div.videopage_block') as $dulce) {
  
              $item['title'] = $dulce-&gt;find('div.academy_text', 0)-&gt;plaintext;
              $item['vimeo_url'] = $dulce-&gt;find('iframe')-&gt;src;
  
              $returnArray[] = $item;
          }
       }
  </code></pre>
  
  <p>This is my result in json:</p>
  
  <pre><code>[
    {
      "title": "How to Ride a Skateboard",
      "vimeo_url": null
    },
    {
      "title": "How to Build a Skateboard",
      "vimeo_url": null
    }
  ]
  </code></pre>
  
  <p>How do I get my iFrame SRC?</p>
  
  <p>I've also tried <code>$item['vimeo_url'] = $dulce-&gt;find('.videopage_video')-&gt;plaintext;</code> and nothing</p>
