$str = '<a href="index.php?do=vote" target="_blank" class="list_server">ลิ้งค์ใช้โหวต</a>';
if(preg_match('/<(.+)>(.+)<\/(.+)>/', $str, $match)) {
	$tag['attribute'] = trim($match[1]);
	$tag['title'] = $match[2];
	$tag['name'] = $match[3];
}
$arr = explode(' ', $tag['attribute']);
unset($arr[0]);
foreach($arr as $index => $val) {
	$arr[$index] = trim($val);
}
$output = implode('&', $arr);
parse_str($output, $attribute);
foreach($attribute as $key => $val) {
	$attribute[$key] = substr(stripslashes($val), 1, -1);
}
$tags[$tag['name']] = $attribute;
