<?
$htmlDom				=	new DOMDocument;

//須要添加meta 避免中文亂碼
$html					=	'<meta http-equiv="Content-Type" content="text/html; charset=utf-8">' . '<div class="aaa">Hellow</div>';

$htmlDom->loadHTML($html);
$divlist				=	$htmlDom->getElementsByTagName("div");
foreach ($divlist as $div)
{

	//取得屬性
	$str				=	$div->getAttribute("class");

	//設定屬性
	$div->setAttribute("data-add", $str);

	//裡面的文字: Hellow
	$value				=	$div->nodeValue;
}

//輸出: <div class="aaa" data-add="aaa">Hellow</div>
echo $htmlDom->saveHTML();

?>
