Exceptions

• ext/dom supports PHP5 exceptions
• not everywhere yet (mostly where DOM standard asks for)

  $dom = new domdocument();
  $dom->load("book.xml");
  $rootNode = $dom->documentElement;
  try {
    $rootNode->appendChild($rootNode);
  } catch (domexception $e) {
    print "Error: $rootNode could not be appended";
  }
