Parsing empty XML elements in PHP - php

Question

PHP newbie here. I'm parsing a long XML file, setting each tag to a variable. If the element's tag is empty, I want to assign it the value "N/A"
I'm wondering if there's a more concise way to do this than my current approach:
$elements = array()
$propertyOwner = $report->PropertyProfile->PrimaryOwnerName[0];
array[] = $propertyOwner;
$propertyAddress = $report->PropertyProfile->SiteAddress[0];
array[] = $propertyAddress;
...
for($i=0; $i<count($elements); $i++) {
if (array[i] === '') {
array[i] = 'N/A');
}
}

The way the code was written originally (without $s in front of each variable) you'd probably be getting errors all day. Hope this helps simplify:
$array[] = '';
$elements = array();
$propertyOwner = $report->PropertyProfile->PrimaryOwnerName[0];
$elements[] = $propertyOwner;
$propertyAddress = $report->PropertyProfile->SiteAddress[0];
$elements[] = $propertyAddress;
//...
// IF THEN ELSE
$array[] = !empty($elements) ? $elements : 'N/A';
