#39365 [Opn->Bgs]: getElementsByTagNameNS() does not return elements in a default namespace

ID: 39365 Updated by: rrichards@php.net Reported By: z_rules55 at hotmail dot com -Status: Open +Status: Bogus Bug Type: DOM XML related Operating System: WinXP Professional PHP Version: 5.2.0 New Comment: 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 You are mixing level 1 and level 2 functionality. Specs also indicate that doing this will lead to unexpected behavior. Must use createElementNS(). Previous Comments: ------------------------------------------------------------------------ [2006-11-04 14:26:26] z_rules55 at hotmail dot com Per the XML spec, setting the xmlns attribute on an element but with no prefix (like I did with $root) sets a default namespace for that element and its descendants. $default_ns_element and $explicit_ns_element, therefore, do not need the xmlns attribute to be in 'my_namespace' because they inherit the namespace from $root by default. ------------------------------------------------------------------------ [2006-11-04 08:03:04] chregu@php.net $xml->createElement('element', 'default_ns_element') That's not in the default namespace, that's in no namespace at all this way. Can't work this way ------------------------------------------------------------------------ [2006-11-03 21:28:54] z_rules55 at hotmail dot com Additional note: getElementsByTagName('element') does, in fact, find both nodes. ------------------------------------------------------------------------ [2006-11-03 21:12:54] z_rules55 at hotmail dot com Description: ------------ Calling getElementsByTagNameNS() on a DOMDocument or a DOMElement does not return elements that are under a default namespace. The example below finds $explicit_ns_element, but not $default_ns_element. Reproduce code: --------------- <?php $xml = new DOMDocument(); $namespace = 'my_namespace'; $root = $xml->appendChild($xml->createElementNS($namespace, 'root')); $default_ns_element = $root->appendChild($xml->createElement('element', 'default_ns_element')); $explicit_ns_element = $root->appendChild($xml->createElementNS($namespace, 'element', 'explicit_ns_element')); foreach($xml->getElementsByTagNameNS($namespace, 'element') as $el) { echo $el->nodeValue."\n"; } echo "\n"; foreach($root->getElementsByTagNameNS($namespace, 'element') as $el) { echo $el->nodeValue."\n"; } ?> Expected result: ---------------- default_ns_element explicit_ns_element default_ns_element explicit_ns_element Actual result: -------------- explicit_ns_element explicit_ns_element ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=39365&edit=1
