help with php DOM function

i have got the following code running, but it still sees a link on an exteranl webpage which is not inside the body tag as valid...not sure whats wrong...

$dom = new DOMDocument();
     @$dom->loadHTML($get_webpage);
   @$dom->getElementsByTagName('body');
      $x = new DOMXPath($dom);

     foreach($x->query("//a") as $node)
       {
            if ($node->getAttribute("href") == "http://www.mysite.com/" && $node->getAttribute("rel") == "" && $node->textContent == "mysite")
                    {
              // echo 'valid link on site';
            }

       }

External webpage

It's because DOM will rewrite the HTML "properly". If you do saveHTML, you will see that the a tag is now in the body tag. I don't think there is a way to change that behavior.

Side note:

Use this:

libxml_use_internal_errors(true);
$dom->loadHTML($data);

Instead of:

@$dom->loadHTML($data);

It's cleaner.
