Example #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();
?>
以上例程会输出：
<?xml version="1.0" encoding="utf-8"?> <root attr="attrvalue" />
