Php Simple_XML类：获取info节点上的属性和信息

我正在使用annapi提取信息。我使用simpleXML类来获取信息

function explodeTest() {
            $result = $this->_restGenerator($this->ann, '6236');
            //print_r($result);
            foreach ($result->anime as $data) {
                print_r($data->info);
            } 
        }

_restGenerator功能：

function _restGenerator($url,$q) {
        $url = $url . strtolower($q);
        if(strlen($q) > 0) {
            $q = file_get_contents($url);
            //$q = simplexml_load_file($url)
            return simplexml_load_string($q);
        }
    }

常数：

$this->ann = 'http://cdn.animenewsnetwork.com/encyclopedia/api.xml?anime=';

当我运行函数时，我得到以下结果：

SimpleXMLElement Object ( [@attributes] => Array ( [gid] => 3506750509 [type] => Picture [src] => http://cdn.animenewsnetwork.com/thumbnails/fit200x200/encyc/A6236-259.jpg ) )

但实际的XML标记显示如下：

<anime id="6236" gid="1601610894" type="TV" name="Gintama" precision="TV" generated-on="2012-07-07T04:58:39Z">

当我打印（$result）。。。信息节点显示如下

我需要获取节点的type属性以使数组可区分，或者至少按type属性过滤info节点

谢谢。

使用获取属性

foreach ($result->anime as $data) {
    foreach($data->info as $info){
        $a = $info->attributes();
        echo $a['type']. "\n";
    }
}
