如何在php中获取没有子元素的xml数据的属性

Question

我正在尝试使用以下xml的simplexml_load_string和SimpleXMLElement使用php函数获取产品（despecid）节点的属性。

<productlist brand="HP" model="Color Laserjet 3000">
   <product despecid="CAN21679">IR C1021/MF8450 Fuser Unit (Fixing Assembly)</product>
   <product despecid="HPRM1-2743-180CN">CLJ 3000/3600/3800 CP3505 fuser unit</product>
   <product despecid="XER003R99755">Xerox XRC toner Q7560A black</product>  
</productlist>

但我从两个（simplexml_load_string和SimpleXMLElement）方法输出中得出如下。

object(SimpleXMLElement)#179 (2) {
["@attributes"]=>
 array(2) {
  ["Brand"]=>
    string(2) "HP"
  ["Model"]=>
    string(19) "Color Laserjet 3000"
 }
 ["Product"]=>
   array(6) {
    [0]=>
     string(44) "IR C1021/MF8450 Fuser Unit (Fixing Assembly)"
    [1]=>
     string(36) "CLJ 3000/3600/3800 CP3505 fuser unit"
    [2]=>
      string(28) "Xerox XRC toner Q7560A black"
    [3]=>
      string(27) "Xerox XRC toner Q7561A cyan"
    [4]=>
     string(29) "Xerox XRC toner Q7562A yellow"
    [5]=>
     string(30) "Xerox XRC toner Q7563A magenta"
   }
}

是否有任何方法可以获得产品的属性。请帮忙...

$xml = <<<XML
<productlist brand="HP" model="Color Laserjet 3000">
   <product despecid="CAN21679">IR C1021/MF8450 Fuser Unit (Fixing Assembly)</product>
   <product despecid="HPRM1-2743-180CN">CLJ 3000/3600/3800 CP3505 fuser unit</product>
   <product despecid="XER003R99755">Xerox XRC toner Q7560A black</product>  
</productlist>
XML;


foreach (simplexml_load_string($xml)->product as $product) {
   print_r($product->attributes()->despecid); 
}
