Question

Here is my code below.

$dom = new DOMDocument(); 
$dom->loadHTML($source); // Html String
$xpath = new DOMXPath($dom);

$meta_keywords = $xpath->query("//meta[translate(@name,'ABCDEFGHIJKLMNOPQRSTUVWXYZ','abcdefghijklmnopqrstuvwxyz') = 'keywords']");


try
{

    if($meta_keywords != null)
    {
         $keyword = $meta_keywords->item(0)->getAttribute("content");

    }
}catch (Exception $e) {
    echo $e->getMessage();
}

Sometimes it works sometimes it doesn’t. And when it doesn’t work it causes my script to exit without errors warnings and without exceptions.

I decided to use TIDY for my HTML strings.
