New Comment:
deep copy works fine, its the modifications to the DOMNodeList causing
the problem.
You will need to do something like:
while ($child = $new_content->childNodes->item(0)) {
$div->appendChild($child);
}
The DOMNodeList returns live (modifyable data), unlike the old 4.x
extension which would return a static array of nodes. This means that
nodes can be added, removed, etc.. from the list using other objects
outside of the DOMNodeList (such as the appendChild method). foreach
should not be used when adding/appending/removing any of the top level
nodes in the nodelist.

Description:
------------
When importing a DOM node from one document into another using
DOMDocument->importNode(), the optional second argument with a value of
TRUE should produce a deep copy of the imported node; that is, all child
nodes of the imported node should be duplicated. (Similar to the effects
of using the optional second argument with cloneNode().) Instead, only
the first child of the imported node is included with the copy.
Notes:
1. This problem is related to the new DOM extension, and not to the old
DOMXML extension.
2. The same problem occurs regardless how the DOMDocument is
instantiated: using LoadHTML(), LoadXML(), LoadHTMLFile(), or
LoadXMLFile() to do so all produce the same (incorrect) result.
3. Per
http://www.w3.org/TR/DOM-Level-2-Core/core.html#Core-Document-importNode
-- "... deep of type boolean ... If true, recursively import the subtree
under the specified node..."; the specific problem here is that the copy
is not done recursively.
Reproduce code:
---------------
<?php
$old_doc = DOMDocument::LoadXML("<html><head><title>OLD
DOCUMENT</title></head><body><p>First paragraph.</p><p>Second
paragraph.</p></body></html>");
$new_doc = DOMDocument::LoadXML("<html><head><title>NEW
DOCUMENT</title></head><body></body></html>");
$old_body = $old_doc->getElementsByTagName("body")->item(0);
$new_body = $new_doc->getElementsByTagName("body")->item(0);
$div = $new_doc->createElement("div");
$div->setAttribute("class", "page");
$new_content = $new_doc->importNode($old_body, TRUE);
foreach($new_content->childNodes as $child)
$div->appendChild($child);
$new_body->appendChild($div);
print "<pre>" . htmlentities( $new_doc->saveXML() ) . "</pre>";
?>
Expected result:
----------------
<?xml version="1.0"?>
<html><head><title>NEW DOCUMENT</title></head><body><div
class="page"><p>First paragraph.</p><p>Second
paragraph.</p></div></body></html>
Actual result:
--------------
<?xml version="1.0"?>
<html><head><title>NEW DOCUMENT</title></head><body><div
class="page"><p>First paragraph.</p></div></body></html>
