PHP - SimpleXML - AddChild with another SimpleXMLElement

Question

I\'m trying to build a rather complex XML document.

I have a bunch of sections of the XML document that repeats. I thought I\'d use multiple string templates as base

As far as I know, you can't do it with SimpleXML because addChild doesn't make a deep copy of the element (being necessary to specify the tag name can easily be overcome by calling SimpleXMLElement::getName()).

One solution would be to use DOM instead:

With this function:

function sxml_append(SimpleXMLElement $to, SimpleXMLElement $from) {
    $toDom = dom_import_simplexml($to);
    $fromDom = dom_import_simplexml($from);
    $toDom->appendChild($toDom->ownerDocument->importNode($fromDom, true));
}

We have for

");

$n1 = simplexml_load_string("one");
$n2 = simplexml_load_string("two");

sxml_append($sxml, $n1);
sxml_append($sxml, $n2);

echo $sxml->asXML();

the output
