DOMNode::C14NFile
If you need some function to clone a node without touching namespaces you can use the following.
<?php
private function cloneNode($node,$doc){
$nd=$doc->createElement($node->nodeName);
foreach($node->attributes as $value)
$nd->setAttribute($value->nodeName,$value->value);
if(!$node->childNodes)
return $nd;
foreach($node->childNodes as $child) {
if($child->nodeName=="#text")
$nd->appendChild($doc->createTextNode($child->nodeValue));
else
$nd->appendChild(cloneNode($child,$doc));
}
return $nd;
}
?>

<?php
//@oliver thanks for example source...
/*
cloneNode(false) does not omit
Attributes of cloned node,
to achieve this an iteration is required.
this is probably less efficient
than merely creating a new
node from the desired nodeName
but in some cases could be useful.
use case:
omit subnodes and attributes of
secured portions of an xml document
without altering expected general structure;

For those converting from PHP 4 DOM XML to PHP 5 DOM extension:
In the old days, DOM XML's clone_node() was the way to copy nodes from one DOM to another, as well as to perform intra-DOM copies. Nowadays, DOM's cloneNode() is the intra-DOM solution, but see importNode() (http://php.net/dom-domdocument-importnode) to copy nodes from one DOM to another.
So to append root node of $dom2 and all its children into root node of $dom1:
PHP 4 (DOM XML):
<?php
$root1 = $dom1->document_element();
$other_node = $dom2->document_element();
$root1->append_child($other_node->clone_node(true));
?>
PHP 5 (DOM):
<?php
$dom1->documentElement->appendChild(
$dom1->importNode($dom2->documentElement, true));
?>
