This does not only affect DocumentFragments. I had this problem with a simple importNode() when
having multiple default namespaces. Here is a simplified XML sample:
Reproduce code:
---------------
<?php
$xml = '<?xml version="1.0" encoding="utf-8"?>
<feed xmlns="http://www.w3.org/2005/Atom">
<div xmlns="http://www.w3.org/1999/xhtml">
<p>Test-Text</p>
</div>
</feed>';
$dom = new DOMDocument();
$dom->loadXML($xml);
$dom2 = new DOMDocument();
$importedNode = $dom2->importNode($dom->documentElement, true);
$dom2->appendChild($importedNode);
echo $dom2->saveXML();
?>
Actual result:
--------------
<?xml version="1.0"?>
<feed xmlns="http://www.w3.org/2005/Atom"
xmlns:default="http://www.w3.org/1999/xhtml">
<default:div xmlns="http://www.w3.org/1999/xhtml">
<default:p>Test-Text</default:p>
</default:div>
</feed>

Description:
------------
Hi,
When I import a DOM node via a document fragment, suddenly a "default" namespace comes out
of nowhere (and it's really hard to remove, short of making my own cloneNode() simulation
stripping it).
IIRC PHP4 got this right (although it had lots of other issues), and all other languages I've
tested in (Perl, Python, Ruby) do as well. Note that the code below doesn't strictly need
importNode(), but I cannot really do with cloneNode() in the real code (it's vastly
simplified).
Note: On the surface, this appears to be the same bug as #46185, but I tested 5.3 CVS (as of
2009-02-28) and it's still there.
Reproduce code:
---------------
<?php
$doc = new DOMDocument;
$doc->loadXML('<html xmlns="something"
xmlns:ns="whatever"><element ns:foo="bar" /></html>');
$root = $doc->documentElement;
$elem = $root->firstChild;
$frag = $doc->createDocumentFragment();
$frag->appendChild($doc->importNode($elem));
$root->appendChild($frag);
print $doc->saveXML();
?>
Expected result:
----------------
<?xml version="1.0"?>
<html xmlns="something" xmlns:ns="whatever"><element
ns:foo="bar"/></html>
Actual result:
--------------
<?xml version="1.0"?>
<html xmlns="something" xmlns:ns="whatever"><default:element
xmlns:default="something" xmlns:ns="whatever"
ns:foo="bar"/></html>
