Question

我有一个这种结构的RSS Feed：

    <?xml version="1.0" encoding="UTF-8"?>
    <rss version="2.0"
        xmlns:media="http://search.yahoo.com/mrss/"
        xmlns:content="http://purl.org/rss/1.0/modules/content/"
        xmlns:wfw="http://wellformedweb.org/CommentAPI/"
        xmlns:dc="http://purl.org/dc/elements/1.1/"
        xmlns:atom="http://www.w3.org/2005/Atom"
        xmlns:sy="http://purl.org/rss/1.0/modules/syndication/"
        xmlns:slash="http://purl.org/rss/1.0/modules/slash/"
        >
    <channel>
        <title>Title</title>
        <atom:link href="url" rel="self" type="application/rss+xml" />
        <link>url</link>
        <description>desc</description>

        <generator>http://wordpress.org/?v=3.8.1</generator>
        <item>
            <title>Hello</title>
            <link>helloUrl/</link>
            <comments>comments</comments>
            <pubDate>Tue, 21 Oct 2014 12:44:18 +0000</pubDate>
            <dc:creator><![CDATA[admin]]></dc:creator>
            <category><![CDATA[General]]></category>       
            <guid isPermaLink="false">permalink</guid>

<wfw:commentRss>feedURL</wfw:commentRss>
<slash:comments>0</slash:comments>


            </item>
            .
            .

为了获取所包含的信息，这是我的php：

<?php
  $url ="myrss.rss";
  $rss = simplexml_load_file($url);
  if($rss)
  {
      echo '<h1>'.$rss->channel->title.'</h1>';
      echo '<li>'.$rss->channel->pubDate.'</li>';
      $items = $rss->channel->item;
      foreach($items as $item)
      {

          $title = $item->title;
          $link = $item->link;
          $published_on = $item->pubDate;
          $description = $item->description;
          echo '<h3><a href="'.$link.'">'.$title.'</a></h3>';
          echo '<span>('.$published_on.')</span>';
          echo '<p>'.$description.'</p>';

          $ns_media = $item->children('http://search.yahoo.com/mrss/');
          echo $ns_media->content; 
      }
  }

所有内容都正在打印，但是对于图片网址。我需要图片网址，以便我可以使用来自RSS Feed的图片和文字构建一个网页。

我做错了什么？

谢谢！

解决：

以防有人需要它：

不要使用simplexml_load_file

使用

  $rss = file_get_contents('myrss.xml');
  $rss = str_replace('<media:', '<', $rss);

PHP：当它们作为多媒体附加时，从Wordpress源中获取图像
