Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php DomNodeListe implements Traversable. You can convert a Traversable object to an Iterator using the IteratorIterator class. <?php $xml = '<queries><query attr1="value"></query></queries>'; $doc = new DOMDocument; $doc->loadXML($xml); $queries = $doc->getElementsByTagName('queries'); $nodes = iterator_to_array(new IteratorIterator($queries)); ?> Previous Comments: ------------------------------------------------------------------------ [2007-01-17 15:11:55] jules_papillon_fh at yahoo dot de This bug exists further reproducibly on PHP5.2 ------------------------------------------------------------------------ [2007-01-17 15:09:11] jules_papillon_fh at yahoo dot de Another Code to reproduce the Bug: ---------------------------------- $dom = new DOMDocument('1.0', 'ISO-8859-1'); $dom->load('file.xml'); $iterator = new RecursiveIteratorIterator($dom->childNodes, RecursiveIteratorIterator::SELF_FIRST); foreach($iterator as $name => $element) { print $name .
