title: get div conents from external url - best method - PHP? DOM? jQuery?
body: <p>I am trying to get the contents of a div from the id name.</p>
  
  <p>Here is the div I am trying to get:  <code>&lt;div id="article-body"&gt; ... &lt;/div&gt;</code></p>
  
  <p>However, this is on another external website so it has to be called with a www or an http:// etc... </p>
  
  <p>I am sure it's possible. Just not sure if I should use PHP, DOM or jQuery etc..</p>
  
  <p>I am thinking this code should be possible to do in a few lines. Just don't know what is the best method. Thanks for the tips or ideas. </p>
  
  <p><strong>UPDATE:</strong> It was suggested this was a duplicate question. It is not. I have used the code from the suggested duplicate question below and it does not work. </p>

  <pre><code>&lt;html&gt;
  
  &lt;body&gt;
  &lt;?
  $doc = new DomDocument;
  
  // We need to validate our document before refering to the id
  $doc-&gt;validateOnParse = true;
  $doc-&gt;loadHtml(file_get_contents('http://www.lifesitenews.com/news/second-madagascar-archbishop-criticizes-catholic-relief-services-full-trans'));
  
  var_dump($doc-&gt;getElementById('article-body'));
