Question

what i want to do is to get an element with its class name and show it as a actual html element not it nodes or its inner data

here is my code

$html = file_get_contents("www.site.com");
$dom = new DOMDocument('1.0');
$dom->loadHTML($html);
$element = $dom->getElementById('myid');
$string = $element->C14N();

here is how i do it using ID but i want to now if there is a way to do this using class apparently there is no getElementByClass method

There is no straightforward method in php dom to do this. You will have to walk all the elements and check if their class attribute contains the class name you need…

$html = file_get_contents("www.site.com");
$dom = new DOMDocument('1.0');
$dom->loadHTML($html);
foreach ($dom->getElementsByTagName('div') as $element) {
    if (strpos($element->getAttribute('class'), 'yourClassNameHere') !== false) {
        $string = $element->C14N();
    }
}

You can also use DOMXpath:

$xpath = new DOMXpath($doc);
foreach ($xpath->query("*/div[@class='yourClassNameHere']") as $element) {
    $string = $element->C14N();
}
