我尝试了太多的方法来从下面的代码中读取 [label] 的值：

    Array ( [0] => 
    SimpleXMLElement Object
    (
       [id] => x 
       [published] => 2011
       [category] =>
     Array ( [0] => 
      SimpleXMLElement Object 
      ( 
      [@attributes] => 
        Array (
        [scheme] => y 
        [term] => t 
        ) )
        [1] => SimpleXMLElement Object 
        ( [@attributes] => 
        Array (
        [scheme] => y2 
        [term] => Film
        [label] => Film & Animation 
        ) )

它以数字数组开头。

    Array ( [0] => 
    SimpleXMLElement Object
    (
       [id] => x 
       [published] => 2011
       [category] =>
     Array ( [0] => 
      SimpleXMLElement Object 
      ( 
      [@attributes] => 
        Array (
        [scheme] => y 
        [term] => t 
        ) )
        [1] => SimpleXMLElement Object 
        ( [@attributes] => 
        Array (
        [scheme] => y2 
        [term] => Film
        [label] => Film & Animation

你的答案是不是很简单：

$data->category['label']?

下次看 simplexml 文档，所有属性都可以从数组访问，所有子节点都可以通过对象属性运算符访问。

如果您有很多类别，那么您将在“category[0]”处有一个数组

Isn't your answer as simple as:

$data->category['label']?

See simplexml documentation next time, all attributes are accessible from an array, and all subnodes are accessible through the object property operator.

If you have many categories, then you will have an array at "category[0]"
