php - getFirstOrderedNode

I'm kicking off my code snippet series with a php function which mimics javascript's "first ordered node" xpath result type. This series isn't really for my regular readers (if i had any) more for the archives.

function getFirstOrderedNode($xpath, $query,  $parent){
  $children = $xpath->query($query, $parent);
  if($children->length != 1){ return null; }
  $child = $children->item(0);
  return $child;
}
