Question

i have some problems to retreive the HTML of a specefic div containing the class name “tabEmbed”

The code works but for some reason, it only returns the txt … no HTML. All the text formating is striped out … normaly there should be embed code as well. What did i miss?

    $dom = new DOMDocument;
    @$dom->loadHTML($Video_Source_HTML);
    $Div_Data           = $dom->getElementsByTagName('div');

    foreach($Div_Data as $Div) {
     if ($Div->getAttribute('id') === 'tabEmbed') {
      $Embed_HTML = $Div->nodeValue;
      if(preg_match('/<input type="text"(.*?)">/is', $Embed_HTML, $Embed)) {
       $Embed_Code = $Embed[1];
      }
     }
    }

First off, you can greatly simplify your code by using DOMDocument::getElementById() in stead of using DOMDocument::getElementsByTagName().

Then, if you’re using a version of PHP equal to, or higher than 5.3.6, you can use DOMDocument::saveHTML() to output the “outerHTML” of the node, like so:

$dom = new DOMDocument;
@$dom->loadHTML( $Video_Source_HTML );

// let's use getElementById() in stead of getElementsByTagName()
$div = $dom->getElementById( 'tabEmbed' );

// be sure to check your browser's source code, or output this as text/plain
echo $dom->saveHTML( $div );

And, as per GordonM’s helpful comment, you could use DOMDocument::saveXML() in PHP versions before 5.3.6, to get acceptable results (depending on the actual content of the original HTML), like so:

echo $dom->saveXML( $div );
