Simple_XML类：获取信息节点上的属性和信息

Question

我正在使用ANN api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);
        }
    }

常量：

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

当我运行该功能时，我得到了这个：

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">

当我执行print_r（$ result）时...信息节点显示为此

[info] => Array ( 
                    [0] => SimpleXMLElement Object ( 
                            [@attributes] => Array ( 
                                                [gid] => 3506750509 
                                                [type] => Picture 
                                                [src] => http://cdn.animenewsnetwork.com/thumbnails/fit200x200/encyc/A6236-259.jpg ) 
                                                ) 
                    [1] => Gintama 
                    [2] => Гинтама 
                    [3] => 銀魂 
                    [4] => ì€í˜¼ 
                    [5] => action 
                    [6] => adventure 
                    [7] => comedy 
                    [8] => drama 
                    [9] => fantasy 
                    [10] => science fiction 
                    [11] => TA 
                    [12] => Twenty years ago .. <synopsis>
                    [13] => 25 
                    [14] => 201 

我需要获取节点的type属性以使数组可以区分，或者至少按类型属性过滤信息节点。

感谢。

Answer 1

使用attributes function获取属性。

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