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 ActÓr</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. </plot> <great-lines> <line>PHP solves all my web problems</line> </great-lines> <rating type="thumbs">7</rating> <rating type="stars">5</rating> </movie> <movie> <title>PHP2: More Parser Stories</title> <plot>This is all about the people who make it work.</plot> <characters> <character> <name>Mr. Parser</name> <actor>John Doe</actor> </character> </characters> <rating type="stars">5</rating> </movie> </movies>
