使用SimpleXmlElement从wordpress RSS订阅获取作者问题

Question

干草，我试图从wordpress博客解析RSS订阅源。到目前为止，一切工作如预期，这里是我的代码

<?php 
    $feedUrl = "FEED URL"; 
    $rawFeed = file_get_contents($feedUrl); 
    $xml = new SimpleXmlElement($rawFeed); 
    $channel = $xml->channel; 
    $items = $channel->item; 
    foreach($items as $item){ 
     echo "<a href='".$item->link."'>".$item->title."</a>"; 
     echo $item->description; 
     echo $item->pubDate; 

    }  

?> 

但是，我似乎有问题得到该职位的作者。数据已经在某个地方，因为当Safari呈现作者出现的Feed时。

这里是我的RSS提要

SimpleXMLElement Object 
(
[@attributes] => Array 
    (
     [version] => 2.0 
    ) 

[channel] => SimpleXMLElement Object 
    (
     [title] => My Blog title 
     [link] => http://blog.com/new/blog 
     [description] => Just another WordPress site 
     [lastBuildDate] => Thu, 22 Jul 2010 08:02:19 +0000 
     [language] => en 
     [generator] => http://wordpress.org/?v=3.0 
     [item] => Array 
      (
       [0] => SimpleXMLElement Object 
        (
         [title] => Second post 
         [link] => http://blog.com/new/blog/?p=5 
         [comments] => http://blog.com/new/blog/?p=5#comments 
         [pubDate] => Thu, 22 Jul 2010 08:02:19 +0000 
         [category] => SimpleXMLElement Object 
          (
          ) 

         [guid] => http://blog.com/new/blog/?p=5 
         [description] => SimpleXMLElement Object 
          (
          ) 

        ) 

       [1] => SimpleXMLElement Object 
        (
         [title] => Hello world! 
         [link] => http://blogl.com/new/blog/?p=1 
         [comments] => http://blog.com/new/blog/?p=1#comments 
         [pubDate] => Thu, 22 Jul 2010 07:22:40 +0000 
         [category] => SimpleXMLElement Object 
          (
          ) 

         [guid] => http://blog.com/new/blog/?p=1 
         [description] => SimpleXMLElement Object 
          (
          ) 

        ) 

      ) 

    ) 

）

任何帮助将是真棒！

感谢

在WordPress的RSS源，作者信息是在<dc:creator>标签。看看它是否也适用于您的Feed。

由于标记名称中含有冒号，XML解析器会吞下该标记。

请参阅this question了解如何让这些标签显示。
