Is there a way to add a PHP SimpleXMLElement to another SimpleXMLElement?

Question

The \"addChild\" method of SimpleXMLElement seems like it should be the right choice, but it apparently only takes strings representing the tagname of the new child.

Answer 1

I'm not sure if this will help but you could also extend SimpleXML to work as you expect. Here is a project I worked on for bLibrary Xml class. You can look at it to tailor SimpleXml to work as you expect it.

Answer 2

Hey unknown. You have to use the DOMElement interface to your SimpleXML objects to achieve this.

<?php

$s = new SimpleXMLElement('<root/>');
$t = new DOMElement('child');

$dom = dom_import_simplexml($s);
$dom->appendChild($t);

echo $s->asXML();
// <root><child/></root>

If you need more specific details, let me know. There are several examples in the documentation and comments for the dom_import_simplexml() method too: http://php.net/dom_import_simplexml
