此XML文件似乎没有与之关联的任何样式信息

Trying to work on a website using Dreamweaver and PHP for development.

On the live site, I suddenly found this error:

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<rss xmlns:content="http://purl.org/rss/1.0/modules/content/" version="2.0">
<channel>
<title>
ABCDED
</title>
<cf:treatAs xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005">list</cf:treatAs>
<link>http://events.sjsu.edu/default.aspx</link>
<description>RSS Feed ABCD Events Calendar</description>
</channel>
</rss>

Actually, are are echoing a XML file into a PHP page ?

$xml = simplexml_load_file('URL');
  foreach ($xml->channel->channel as $value){ 
    $var1 = $value->link;
    $var2 = $value->description;
} 
echo $var1."<br>".$var2;

Display it in php.

Hope it works!
