PHP如何取XML中数据
'http://box.zhangmen.baidu.com/x?op=12&count=1&title=大约在冬季$$齐秦$$$$'
这个接口提供了xml格式的文件，我用$xml = file_get_contents ( 'http://box.zhangmen.baidu.com/x?op=12&count=1&title=大约在冬季$$齐秦$$$$');取出来xml后如何得到里面的值，求PHP大神写出部分代码给我参考，感激不尽。

  $xml = file_get_contents('http://box.zhangmen.baidu.com/x?op=12&count=1&title=大约在冬季$$齐秦$$$$');<br />        $result = simplexml_load_string($xml);<br />        var_dump($result);
