帮助设置PHP SimpleXML

Question

I'm having trouble getting PHP's SimpleXML to work with our XML feed. I'm just calling the title attribute for simplification. When I run any of this code it only exports empty h3 tags. Any help is greatly appreciated.

I've tried this:

        <?php
        $xml = simplexml_load_file('http://events.stanford.edu/xml/mobile.xml');

        foreach($xml as $event){
            echo '<h3>', $event['title'], '</h3>';
        }

        ?>

...and this:

        <?php
        $xml = simplexml_load_file('http://events.stanford.edu/xml/mobile.xml');

        foreach($xml->Event as $event){
            echo '<h3>', $event['title'], '</h3>';
        }

        ?>

...and this:

        <?php
        $xml = simplexml_load_file('http://events.stanford.edu/xml/mobile.xml');

        foreach($xml as $node){
            echo '<h3>', $node['title'], '</h3>';
        }

        ?>
