[PHP] Missing namespaceURI after importNode()

[Tim Lind]

Hi

I am importing a node into a new document so that I can perform an XSL 
transformation on just that node. This works sometimes, however, I've 
come into the following problem, where the namespaceURI is there on the 
node but doesn't make it through the importNode() to the next document.

Can you tell me what might be the cause of loosing the namespace on 
importing the node? Bearing in mind that the childnode itself (being the 
result of an xsl transformation) was previously imported into the 
document as a replacement for it's original node.

I'm using PHP 5 DOM and XSL extensions.

CODE SNIPPET:


# ...$childNode exists previous to this point

echo "\n --- source node --- \n";

echo $this->srcDocument->saveXML($childNode);
var_dump($childNode->namespaceURI);

# importing childnode into a new doc

$newDoc = new DOMDocument();
$newRoot = $newDoc->importNode($childNode, true);
$newDoc->appendChild($newRoot);

echo "\n --- import of source node --- \n";

echo $newDoc->saveXML($newRoot);
var_dump($newRoot->namespaceURI);

# will be using newDoc for an XSL transformation and replacing childNode
# with the new doc,
# (which is what was previously done successfully with child node)


OUTPUT SNIPPET:

 --- source node ---
<pre:name/>string(15) "xtc:website.com"


 --- import of source node ---
<name/>NULL
