Pluck structured data?

Use the example (see below) before with the $key, that last one does not work.

<?php
$subaktuelles = $site->index()->findBy("uid", "aktuell")->children()->visible();
$neuigkeiten = new Structure();
$key = 0;
foreach($subaktuelles as $p) {
  foreach($p->news()->toStructure() as $item) {
    $neuigkeiten->append($key, $item);
    $key++;
  }
}

foreach ($neuigkeiten->sortBy('date', 'desc') as $neuigkeit): ?>
