Answer

The quickest way is to use simpleXML, array_map and xpath.

$xml = simplexml_load_file("test.xml")

$arrayCatNames = array_map('strval', $xml->xpath('//CATEGORY_FULLNAME'));

$xml->xpath returns an array of simple XML elements. ‘//CATEGORY_FULLNAME’ searches for the tag anywhere in the XML. With array_map the function strval is applied to all elements to get the values.
