title: Scrape iframe embed code
body: <p>I have a simple php scrape that I have managed to set up that grabs the title and image off a page</p>
  
  <pre><code>$post=$_POST['post'];
  
  $html = file_get_html($post);
  $title = $html-&gt;find('h2', 1);
  $imageurl = $html-&gt;find('img', 1); 
  
  echo $title-&gt;plaintext."&lt;br&gt;\n";
  echo $imageurl-&gt;src;
  </code></pre>
  
  <p>But Im also trying to grab the video embed code, that uses an iframe like this</p>
  
  <pre><code> &lt;input type="text" name="media_embed_code" id="mediaEmbedCodeInput" size="110" onclick="this.focus();this.select();" value="&amp;lt;iframe src=&amp;quot;http://drunksportsfans.com/embedframe/537&amp;quot; frameborder=0 width=510 height=400 scrolling=no&amp;gt;&amp;lt;/iframe&amp;gt;"&gt;
  </code></pre>
  
  <p>I just need the value part, but its clearly more complicated than the title and image</p>
