仅输出XML对手的名字，无论是在家还是离开

Question

I'm using PHP to output data from a sports XML file (in this example it's men's basketball). The XML file features home name ("hn") and visitor name ("vn"), for example the latest score's h3 is "Oregon State vs Stanford."

My question is, how can the h3 display only the opponent's name, regardless of whether they're home or away (in other words, it shouldn't say "Stanford", just the opponent's name, i.e. "Oregon State").

Here's my page and code:

    <?php
    $xml = simplexml_load_file('http://www.gostanford.com/data/xml/events/m-baskbl/2010/index.xml');

    // Reverse chronological order
    $xmlArray = array();
    foreach ($xml as $event_date) $xmlArray[] = $event_date;
    $xmlArray = array_reverse($xmlArray);

    foreach ($xmlArray as $event_date) {
        if(!empty($event_date->event['vn']) && !empty($event_date->event['hn']) && !empty($event_date->event['vs']) && !empty($event_date->event['hs']))
        {
                echo '<li>';
                    echo '<h3>', $event_date->event['vn'], ' vs ', $event_date->event['hn'], '</h3>';
                    echo '<p><strong>', $event_date->event['vn'], ' ', $event_date->event['vs'], ' - ', $event_date->event['hn'], ' ', $event_date->event['hs'], '</strong></p>';
                    echo '<p>', date('F j, Y', strtotime($event_date['date'])), '</p>';
                echo '</li>';
        }
    }   
    ?>

Thanks for your help!

Change

 echo '<li>';
      echo '<h3>', $event_date->event['vn'], ' vs ', $event_date->event['hn'], '</h3>';

to

 $name = ($event_date->event['vc'] == 'stan') ? $event_date->event['hn'] : $event_date->event['vn'];
 echo '<li>';
      echo '<h3>', $name, '</h3>';
