How to merge xml objects?

Question

How can I combine two or more simpleXML objects?

$xml1 = simplexml_load_file($file1);
$xml2 = simplexml_load_file($file2);
...

What do you mean by "combine"? Please show examples of input and output. — hmakholm left over Monica, Sep 08 '11 at 19:04
like when you merge two arrays... But in this case they would be simplexml objects :D — Anne M, Sep 08 '11 at 19:06

You can typecast the XML into an array, merge ( http://php.net/manual/en/function.array-merge.php) it, then typecast back to an object. Like so:

$xml = (object)array_merge((array)$xml1, (array)$xml2);

You can create a new class and add those objects to the class to get a combined object.

class myXML {
  function add($xmlobj) {
    foreach ($xmlobj->children() as $key=>$obj) {
        $this->$key = $obj;
    }
  }
}

$xob1 = simplexml_load_file($file1);
$xob2 = simplexml_load_file($file2);
$xob3 = new myXML();
$xob3->add($xob1);
$xob3->add($xob2);
