title: SimpleHTMLDOM - Get iframe src link
body: <p>How to get the "thesrc" link from the iframe tag with SimpleHTMLDOM?</p>
  
  <p>The source of the page i want the data from:</p>
  
  <pre><code>&lt;div class="ui-tab-pane" data-role="panel" id="feedback"&gt;
   &lt;iframe scrolling="no" frameborder="0" marginwidth="0" marginheight="0" 
  width="100%" height="200" 
  thesrc="//feedback.aliexpress.com/display/productEvaluation.html?productId=32795263337&amp;ownerMemberId=228319068&amp;companyId=237873399&amp;memberType=seller&amp;startValidDate=&amp;i18n=true"&gt;&lt;/iframe&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>So i tried:</p>
  
  <pre><code>&lt;?php
  include_once('simple_html_dom.php');
  
  $html = file_get_html('https://www.aliexpress.com/item/Global-Version-Xiaomi-Redmi-Note-4-Mobile-Phone-3GB-RAM-32GB-ROM-Snapdragon-625-Octa-Core/32795263337.html');
  $dom = new DOMDocument();
  $dom-&gt;loadHTML($html);
  $xpath = new DOMXpath($dom);
  foreach ($xpath-&gt;query("//div[#class='ui-tab-pane']") as $node){
  echo $node-&gt;getElementsByTagName('iframe')[0]-&gt;getAttribute("thesrc");
  echo $node-&gt;getElementsByTagName('div')[0]-&gt;nodeValue;
  }
  
  ?&gt;
  </code></pre>
  
  <p>It returns nothing. What i'm doing wrong?</p>
