返回xpath屬性

Question

我試圖返回「標籤」屬性的值，但沒有成功。我堅持笑

$dom = new DOMDocument(); 
@$dom->loadHTML($source); 
$xml = simplexml_import_dom($dom); 
$code = $xml->xpath("//toolbarbutton"); 
var_dump($code); 

(
    [0] => SimpleXMLElement Object 
     (
      [@attributes] => Array 
       (
        [label] => Hello World 
        [cmd] => redirect 
        [mode] => true 
       ) 

     ) 

) 

Answer 1

嘗試使用

$attr = $code[0]->attributes(); 
echo $attr['label'];
