PHP if variables are not empty, echo

Question

I'm working with this XML file that has some empty attributes, in which case I want to skip that entire attribute's list item. Unfortunately my code still shows everything, even if one of the attributes are empty. I'm sure there's a simpler (and working) way to do this. Here's my page and code:

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

foreach($xml as $event_date){
    if(isset($event_date->event['vn']) && isset($event_date->event['hn']) && isset($event_date->event['vs']) && isset($event_date->event['hs']))
    { 
        echo '<li>';
        echo '<h3>', $event_date->event['vn'], ' vs ', $event_date->event['hn'], '</h3>';
        echo '<p><strong>', $event_date->event['local_time'], '</strong></p>';
        echo '<h3>', $event_date->event['vs'], ' - ', $event_date->event['hs'], '</h3>';
        echo '</li>';   
    }
}

Replace your isset with !empty

I discovered one problem with this. If either team was shutout, i.e. scored a "0", the entire score is excluded. How can this be edited to include zeros? isset won't work, as it includes empty results, which I definitely want to avoid.

@Ryan: well, you need to use compose condition with isset and strlen as @mario proposed :-S

I'm not sure how to do that and don't see @mario's response. Do you know how I can do this? Thank you :)

@Ryan: isset($var) && strlen($var)
