Bug Type: Feature/Change Request
Operating System: *
PHP Version: 5.1.5
New Comment:
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"
------------------------------------------------------------------------
