function DOMinnerHTML($element, $mb_convert_encoding = false) {
	$innerHTML = ""; 
	$children = $element->childNodes; 
	foreach ($children as $child) { 
		$tmp_dom = new DOMDocument(); 
		$tmp_dom->appendChild($tmp_dom->importNode($child, true)); 
		$innerHTML.=trim($tmp_dom->saveHTML());
	}
	if (!$mb_convert_encoding) {
		return $innerHTML;
	}
	else {
		return mb_convert_encoding($innerHTML, $mb_convert_encoding, 'HTML-ENTITIES');
