I'm new to PHP and XML, but I think others might pull their hair out over this too. I forgot
about XML and whitespace when I was populating an array with node values, and was getting what
appeared to be duplicate values despite using array_unique(). Use trim() when populating an array or
assigning a variable.
<?php
$xml_array = array();
foreach ($resource->xpath($node_match) as $option){
$xml_array[$i] = trim($option);
$i++;
}
$xml_unique_array = array_unique($xml_array);
?>
