使用simplexml_load_file从XML提要提取数据

Question

我试图使用simplexml_load_file从XML提要提取数据。这是我现在有：

<?php 
     $anobii = simplexml_load_file('http://www.anobii.com/rss_shelf?s=01fe251a6c442bbf8a'); 
     foreach ($anobii->entry as $anobiiinfo): 
      $title=$anobiiinfo->rss->channel->item->title; 
      $desc=$anobiiinfo->rss->channel->item->description;  
      echo "<span> ",$title,"</span><br><span> ",$desc,"</span>"; 
     endforeach; 
    ?> 

的问题是，我不知道正确的分隔符告诉脚本它需要提取的部分（rss->channel->item->title）。

Answer 1

Yous应遵循xml树结构来获取单个项目。

<?php 
     $feedUrl = 'http://www.anobii.com/rss_shelf?s=01fe251a6c442bbf8a'; 
     $rawFeed = file_get_contents($feedUrl); 
     $anobii = new SimpleXmlElement($rawFeed); 

     foreach ($anobii->channel->item as $anobiiinfo): 
      $title=$anobiiinfo->title; 
      $desc=$anobiiinfo->description;  
      echo "<span> ",$title,"</span> <br/> <span> ",$desc,"</span>"; 
     endforeach; 
    ?>
