Answer 2

$element = $this->dom->getElementById($id);
$element->parentNode->removeChild($element);

Answer 3

getElementsByTagName() returns "live" result that you remove the elements from the DOM. Copy it to an array to get a fixed list.

$druzenja = iterator_to_array(
  $this->dom->getElementsByTagName('druzenje')
);

foreach ($druzenja as $node) {
  if ($node->getAttribute('id') == $id) {
    $node->parentNode->removeChild($node);
  }
}

Xpath would allow you to use more complex conditions. The result is not live.

$xpath = new DOMXpath($this->dom);
foreach ($xpath->evaluate('//druzenje[@id="'.$id.'"]') as $node) {
  $node->parentNode->removeChild($node);
}
