Thank you for taking the time to write to us, but this is not
a bug. 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));
?>

This bug exists further reproducibly on PHP5.2

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 . "\n";
}
Expected result:
----------------
A recursive List of all Elements
Actual result:
--------------
"Catchable fatal error: Argument 1 passed to RecursiveIteratorIterator::__construct() must
implement interface Traversable, instance of DOMNodeList given, called in [ ] and defined in
[ ]"
------------------------------------------------------------------------

Description:
------------
Currently, a DOMNodeList object can be traversed using a foreach loop, but it cannot be converted to
an array using iterator_to_array(), as it produces an error "Warning: iterator_to_array()
expects parameter 1 to be Traversable, object given"
Reproduce code:
---------------
$xml = '<queries><query
attr1="value"></query></queries>';
$doc = new DOMDocument;
$doc->loadXML($xml);
$queries = $doc->getElementsByTagName('queries');
$nodes = iterator_to_array($queries);
Expected result:
----------------
The nodes in the NodeList are returned as an array.
Actual result:
--------------
"Warning: iterator_to_array() expects parameter 1 to be Traversable, object given"
------------------------------------------------------------------------
