Bug #34276 setAttributeNS doesn't work with non-prefixed attributes from default namespace
Submitted: 2005-08-27 02:26 UTC Modified: 2005-08-28 18:27 UTC

Status: Closed Package: DOM XML related

Description:
------------
It's not possible to use hasAttributeNS and getAttributeNS on attributes from the default namespace (i.e. without namespace prefix). They do not find the right attribute.

In addition to this, setAttributeNS cannot set an attribute in the default namespace. The new atttribute gets an incorrect namespace prefix.

I'm using the latest source snapshot php5-200508262230 (standard configuration but --without-pear) with libxml 2.6.20 (-r2 in Gentoo Portage).

Is this a libxml problem, like many DOM extension bugs before? Or do I misunderstand DOM 2 Core / XML Namespaces?

Reproduce code:
---------------
<?php
$dom = DOMDocument::loadXML('<a xmlns="http://namespaces.molily.de/x" xmlns:y="http://namespaces.molily.de/y" attra="attra" y:attrb="attrb" />');
$b = $dom->documentElement;
var_dump($b->hasAttributeNS('http://namespaces.molily.de/x', 'attra'));
var_dump($b->hasAttributeNS('http://namespaces.molily.de/y', 'attrb'));
var_dump($b->getAttributeNS('http://namespaces.molily.de/x', 'attra'));
var_dump($b->getAttributeNS('http://namespaces.molily.de/y', 'attrb'));
$b->setAttributeNS('http://namespaces.molily.de/x', 'attra', 'attra neu');
$b->setAttributeNS('http://namespaces.molily.de/y', 'attrb', 'attrb neu');
$b->setAttributeNS('http://namespaces.molily.de/x', 'attrc', 'attrc');
$b->setAttributeNS('http://namespaces.molily.de/y', 'attrd', 'attrd');
echo("\n");
var_dump($b->getAttributeNS('http://namespaces.molily.de/x', 'attra'));
var_dump($b->getAttributeNS('http://namespaces.molily.de/y', 'attrb'));
var_dump($b->getAttributeNS('http://namespaces.molily.de/x', 'attrc'));
var_dump($b->getAttributeNS('http://namespaces.molily.de/y', 'attrd'));
echo("\n");
var_dump($b->attributes->length);
echo($dom->saveXML());
?>

Expected result:
----------------
(As far as I know:)

bool(true)
bool(true)
string(5) "attra"
string(5) "attrb"

string(9) "attra neu"
string(9) "attrb neu"
string(5) "attrc"
string(5) "attrd"

int(4)
<?xml version="1.0"?>
<a xmlns="http://namespaces.molily.de/x" xmlns:y="http://namespaces.molily.de/y" attra="attra neu" y:attrb="attrb neu" attrc="attrc" y:attrd="attrd"/>

Actual result:
--------------
bool(false)
bool(true)
string(0) ""
string(5) "attrb"

string(0) ""
string(9) "attrb neu"
string(0) ""
string(5) "attrd"

int(5)
<?xml version="1.0"?>
<a xmlns="http://namespaces.molily.de/x" xmlns:y="http://namespaces.molily.de/y" attra="attra" y:attrb="attrb neu" y:attra="attra neu" y:attrc="attrc" y:attrd="attrd"/>

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 misunderstood DOM 2 Core / XML Namespaces. Attributes dont  inherit from default namespace.
