cannot read xml external feed despite having correct url
<p>I'm trying to read the contents of an external xml feed. When I view the link in the browser it renders the xml contents as it should, but when I run it in my browser I get errors.  My code is as follows: </p>

<pre><code>&lt;?php
$url = "http://www.thebigchoice.com/feeds/job_xml.php";

$xml = simplexml_load_file($url); 

print_r($xml);
?&gt;
</code></pre>

<p>Here is the error that I'm getting: </p>
