DOMAttr::__construct()

- $value

范例
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" />
