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):
<?
$root1 = $dom1->document_element();
$other_node = $dom2->document_element();
$root1->append_child($other_node->clone_node(true));
?>
PHP 5 (DOM):
<?
$dom1->documentElement->appendChild(
$dom1->importNode($dom2->documentElement, true));
?>
