用PHP 通过DOM方式创建一个book.xml文件

<?php
    header("content-Type:taxt/html;charset=utf-8");
 $doc = new DOMDocument('1.0','utf-8');
 $bookshelf = $doc ->createElement('bookshelf');
 $doc ->appendChild($bookshelf);
 $book = $doc ->createElement('book');
 $title = $doc ->createElement('title');
 $title ->nodeValue = '天龙八部';
 $book ->appendChild($title);
 $bookshelf -> appendChild($book);
 $doc ->formatOutput = false;
 $doc ->save('newbook.xml');
?>
