Question

I would like to add an element node in my XML file using PHP. I can not get it right when I add it below root.
Please show me some clean code so that I understand how it works. Thank you!
My xml is

<?xml version="1.0" encoding="utf-8"?>
<GameStore>

    <Game type="adventure">
    <TITLE>Assassin's Creed: Brotherhood</TITLE>
    <PUBLISHER>Ubisoft</PUBLISHER>
    </Game> 

    <Game type="adventure">
    <TITLE>Batman: Arkham Asylum</TITLE>
    <PUBLISHER>Eidos</PUBLISHER>
    </Game>

    </GameStore>

If you want to add a new game element, simplexml handles this pretty convenient. Example ($data is obviously your xml):

$xml = simplexml_load_string($data);
$game = $xml->addChild("game");
$game->addAttribute("type", "Game type");
$game->addChild("title", "Game title");
$game->addChild("publisher", "Game publisher");

echo $xml->saveXML();

This will append a “game” child to your xml. We then append two children (title, publisher) to game.
