xml addChild but what about it's sister?!

[rpflorence]

Still very new to PHP but learning very quickly thanks to a few tips here and google.

I'm trying to tackle xml. I have figured out how to add information using addChild but ran into a snag.

Say for example I'm trying to create this into an xml file:

<movies>
  <movie>
    <title>Stardust</title>
    <characters>
      <character>
        <name>Tristan</name>
        <actor>Charlie Cox</name>
      </character>
      <character>
        <name>Yvaine</name>
        <actor>Claire Danes</actor>
      </character>
    </characters>
  </movie>
</movies>

I can create that whole thing except for under characters I can't figure out how to add more than one. I could create it with this code and get just Tristan played by Charlie Cox, but I don't even know how to approach getting a second character in (all of my attempts either fail miserably or just add another name and actor to the first character rather than creating a unique "sister").

Here's my code to get one character in.

$xml = new SimpleXMLElement('new.xml', null, true);

$movie = $xml->addChild('movie');
$movie->addChild('title','Stardust');
$movie->addChild('characters');
$movie->characters->addChild('character');
$movie->characters->character->addChild('name','Tristan');
$movie->characters->character->addChild('actor','Charlie Cox'); 

Thanks!
