How would I check if an XML element exists in PHP?

Wrap it in an if that checks for the existence first…

if($status->item(0)) {
$eventStatus = $status->item(0)>getAttributeNode(“value”)->value;
}

and run from there, I haven’t actually run your script but that’s the basic concept.

You might also look into the SimpleXML stuff, not quite as powerful but awfully easy to get around and does just about everything you’ll want (then you can use the DOM stuff to fill in the blanks)

agreed with funkdaddy.
foreach($somethings as $something){
if($value){
do something here
}
can also do something here for if the value is not set, like assign it if you want
}

if will occur as long as the value is not null, a whitespace character, or zero. all other values will trigger the if
