I tried this, with several variations,
and I have come to the conclusion that it is impossible
to add a tree to a node as I asked using only simplexml functions.
If you have such a solution, I would love to see it.
If you would like an example, I might want to add the item:
<book>
<author>Smith, J</author>
<title>PHP for dummies</title>
<publisher>OUP</publisher>
</book>
My solution, for what it is worth, is something like
-------------------------------------
$docA = new DOMDocument;
$docB = new DOMDocument;
$docB->loadXML($book);
$xpath = new DOMXPath($docB);
$nodes = $xpath->query('//catalog/book');
foreach($nodes as $n) {
$new = $docA->importNode($n, true);
$docA->documentElement->appendChild($new);
}
$output = $docA->save("/tmp/catalog.xml");
