Example #1 Add attributes and children to a SimpleXML element

<?phpinclude 'example.php';$sxe = new SimpleXMLElement($xmlstr);$sxe->addAttribute('type', 'documentary');$movie = $sxe->addChild('movie');$movie->addChild('title', 'PHP2: More Parser Stories');$movie->addChild('plot', 'This is all about the people who make it work.');$characters = $movie->addChild('characters');$character  = $characters->addChild('character');$character->addChild('name', 'Mr. Parser');$character->addChild('actor', 'John Doe');$rating = $movie->addChild('rating', '5');$rating->addAttribute('type', 'stars'); echo $sxe->asXML();?>

以上例程的输出类似于:


<?xml version="1.0" standalone="yes"?>
<movies type="documentary">
 <movie>
  <title>PHP: Behind the Parser</title>
  <characters>
   <character>
    <name>Ms. Coder</name>
    <actor>Onlivia Actora</actor>
   </character>
   <character>
    <name>Mr. Coder</name>
    <actor>El Act&#xD3;r</actor>
   </character>
  </characters>
  <plot>
   So, this language. It's like, a programming language. Or is it a
   scripting language? All is revealed in this thrilling horror spoof
   of a documentary.
