Bug #43221 SimpleXML adding default namespace in addAttribute

Namespace support in SimpleXML is all screwy. In particular, you cannot add two differently-namespaced attributes to a SimpleXML node; the first one is lost.

Reproduce code:
$xml = new SimpleXMLElement('<root />');
$n = $xml->addChild("node", "value");    // still fails even if we set a NS here
$n->addAttribute("a", "b");    // still fails even if we set a different NS here
$n->addAttribute("c", "d", "");

Expected result:
<root xmlns:a=""><node a="b" a:c="d">value</node></root>

Actual result:
<root><node xmlns="" a="b" c="d">value</node></root>

It works just fine if you define your namespace beforehand.

$xml = new SimpleXMLElement('<root xmlns:bar=""/>');
$n = $xml->addChild("node", "value");
$n->addAttribute("a", "b");
$n->addAttribute("c", "d", "");

I don't know, perhaps SimpleXML should raise a E_NOTICE on unknown namespace, but it's really a matter of good coding practice.

Btw, jevon, I don't recommend saying that something is "screwy" when filing bug reports, it doesn't really motivate developpers of said software to look into them ^^;

updated summary.

The bug is that an unprefixed attribute is being allowed to be created with a namespace and a default namespace is being added to the parent element.

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
Thank you for the report, and for helping us make PHP better.

Note that all the examples here will now cause a warning due to trying to create invalid XML.
