Try this:

$html = <<
    
        
            
                
                    check
                
            
        
    
;
HTML;

$dom = new DOMDocument();

$dom->loadHTML($html);

$xpath = new DOMXPath($dom);

$div = $xpath->query('//div[@class="under"]');

$div = $div->item(0);

echo $dom->saveXML($div);



This will output:


    
        check
