SimpleXML: Mixing With DOM Interoperability

PHP SimpleXML Step By Step Tutorial - Part 7: When we work with unknown elements, we can use DOM interoperability. First, we import nodes into the DOM extension. Next, access them using DOM properties and methods. See this sample:

<?php
$lib  = simplexml_load_file("test.xml");

$children = $lib->book->children();

foreach($children as $child){
  $element = dom_import_simplexml($child);
  $name = $element->nodeName;
  print $name.": ".$child;
  
}

?>
