创建文档类型声明
一般而言，XML声明放在文档顶部。在PHP中声明十分简单：只需实例化一个DOM文档类的对象并赋予它一个版本号。查看程序清单A：
程序清单 A
<?php

// display document in browser as plain text
// display document in browser as plain text ......

        [System.Runtime.Serialization.DataMemberAttribute()]
        public Information Archive {

<script type="text/javascript">
var xmlUrl="news.xml";
var swfURL="news.swf";
var img_Speed=2;
var page_Speed=3000;
var TextPosition="down";
var HeadlineColor="#ff0000";
var HeadlineFont="14px";

string file = "c:\\work.xml";
        private void btnCearte_Click(object sender, EventArgs e)
        {
            XmlDocument doc = new XmlDocument();

<bookstore>
<book genre="fantasy" ISBN="2-3631-4">
<title>Oberon's Legacy</title>
<author>Corets, Eva</author>
