如何从<content：encoded>标签中的XML获取2个CDATA值？

Question

我使用笨的框架，我有一个xml文件与下面的代码：

<rss xmlns:content="" xmlns:wfw="" xmlns:dc="" xmlns:atom="" xmlns:sy="" xmlns:slash="" version="2.0"> 
    <channel> 
     <item> 
      <title>Title1</title> 
      <link>Link</link> 
      <pubDate>Date</pubDate> 
      <content:encoded> 
       <![CDATA[ This is description 1 ]]> 
       <![CDATA[ This is description 2 ]]> 
      </content:encoded> 
     </item> 

     <item> 
      <title>Title2</title> 
      <link>Link2</link> 
      <pubDate>Date2</pubDate> 
      <content:encoded> 
       <![CDATA[ This is description 3 ]]> 
       <![CDATA[ This is description 4 ]]> 
      </content:encoded> 
     </item> 
</channel> 
</rss> 

我尝试这样来解析xml：

<?php 
function test() 
{ 
    $xml = simplexml_load_file('http://localhost/testxml/testxml.xml','SimpleXMLElement',LIBXML_NOCDATA); 
    echo "<pre>"; 
    print_r($xml); 
    echo "</pre>"; 
} 
?> 

这是给我的输出，而不CDATA这是否存在于此标签内容：编码：

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

    [channel] => SimpleXMLElement Object 
     (
      [item] => Array 
       (
        [0] => SimpleXMLElement Object 
         (
          [title] => Title1 
          [link] => Link 
          [pubDate] => Date 
         ) 

        [1] => SimpleXMLElement Object 
         (
          [title] => Title2 
          [link] => Link2 
          [pubDate] => Date2 
         ) 

       ) 

     ) 

) 

我怎样才能得到<content:encoded><![CDATA[ This is description 1 ]]><![CDATA[ This is description 2 ]]></content:encoded>这个数据解析？

Answer 1

我得到的答案也一样，我所做的是：

<?php 
function getFeed() { 
     $feed_url = 'http://localhost/testxml/testxml.xml'; 
     $feeds = file_get_contents($feed_url); 
     $feeds = str_replace("<content:encoded>","<contentEncoded>",$feeds); 
     $feeds = str_replace("</content:encoded>","</contentEncoded>",$feeds); 
     $rss = simplexml_load_string($feeds); 

     foreach($rss->channel->item as $entry) { 
      echo ("<a href='$entry->link' title='$entry->title'>" . $entry->title . "</a>"); 
      echo ("$entry->contentEncoded"); 
     } 
    } 
?>
