示例 #1 Creating a new DOMAttr object

<?php

$dom
= new DOMDocument('1.0', 'iso-8859-1');
$element = $dom->appendChild(new DOMElement('root'));
$attr = $element->setAttributeNode(new DOMAttr('attr', 'attrvalue'));
echo
$dom->saveXML();

?>

以上示例会输出:

 
<?xml version="1.0" encoding="utf-8"?>
<root attr="attrvalue" />
