Question

背景：我正在编写一段PHP代码，它使用RESTful API连接到另一方。我正在使用Laravel 4.2，PHP5.5，并使用Guzzle作为客户端。

目前我正在尝试通过API获取一些数据，这会返回一个XML对象。

代码：

public function getCategories()
{
    $client = new Guzzle();

    $req = $client->createRequest('get', $this->api_url."cateservice/category", [
        'headers'=> [
            'Content-type'      => 'application/xml',
            'Accept-charset'    => 'utf-8',
            'openapikey'        => $this->api_key
        ]
    ]);
    $xml = $client->send($req)->getBody();
}

如果我要运行simplexml_load_string($xml)，它将返回一个完全空的对象。如果我使用Guzzle的默认->xml()函数，也一样。

使用浏览器，我设法得到了支持的响应主体：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

问题：我如何解析这段XML，使它成为一个数组，一个PHP对象，或任何允许我访问/循环这些“类别”的东西？

编辑：我正在尝试遍历这些类别，以便我可以处理并将它们存储到我的数据库中。当所有函数返回空对象或空数组时，我对如何处理这个问题一无所知。

在PHP中读取这段XML
