PHP如何取XML中資料

'http://box.zhangmen.baidu.com/x?op=12&count=1&title=大約在冬季$$齊秦$$$$'
這個介面提供了xml格式的檔案，我用$xml = file_get_contents ( 'http://box.zhangmen.baidu.com/x?op=12&count=1&title=大約在冬季$$齊秦$$$$');取出來xml後如何得到裡面的值，求PHP大神寫出部分代碼給我參考，感激不盡。

  $xml = file_get_contents('http://box.zhangmen.baidu.com/x?op=12&count=1&title=大約在冬季$$齊秦$$$$');        $result = simplexml_load_string($xml);        var_dump($result); 

列印結果

object(SimpleXMLElement)[1]  public 'count' => string '1' (length=1)  public 'url' =>     object(SimpleXMLElement)[2]      public 'encode' =>         object(SimpleXMLElement)[5]      public 'decode' =>         object(SimpleXMLElement)[6]      public 'type' => string '8' (length=1)      public 'lrcid' => string '14706' (length=5)      public 'flag' => string '1' (length=1)  public 'durl' =>     object(SimpleXMLElement)[3]      public 'encode' =>         object(SimpleXMLElement)[7]      public 'decode' =>         object(SimpleXMLElement)[8]      public 'type' => string '8' (length=1)      public 'lrcid' => string '14706' (length=5)      public 'flag' => string '1' (length=1)  public 'p2p' =>     object(SimpleXMLElement)[4]      public 'hash' => string 'd1cae9f7634c5aa3d54d7b1b1ad4c5b79b6e97ff' (length=40)      public 'url' =>         object(SimpleXMLElement)[9]      public 'type' => string 'mp3' (length=3)      public 'size' => string '5710896' (length=7)      public 'bitrate' => string '192' (length=3)

encode裡面的資料。。請問該怎麼辦，那個object(SimpleXMLElement)[5]的值怎麼取出來。。

回複討論(解決方案)

$xml = file_get_contents('http://box.zhangmen.baidu.com/x?op=12&count=1&title=大約在冬季$$齊秦$$$$');          $result = simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA);var_dump($result->url->decode);

$xml = file_get_contents('http://box.zhangmen.baidu.com/x?op=12&count=1&title=大約在冬季$$齊秦$$$$');$result = simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA);$ret = (array)$result->url;echo $ret['encode']."
";echo $ret['decode'];

百度知道上已經有人給解答了，用DOM實現的，感覺沒有你們寫的簡單。因為我不會PHP文法，所以這麼簡單的問題不會。。大家都對，結貼給分。
