文档被存档之后，如果你再打开这个文档，那么则会以如下代码列表形式出现：
MyXMLDoc.xml:
1<rootelement>
2<childelement1></childelement1>
3<childelement2></childelement2>
4</rootelement>
在"MyXMLDoc.xml"文档中，childElement1 和 childElement2 会以空的elements形式出现。如果它们被赋值，那么每
个值都将由标记符括起来。
现在，让我们来思考一下如何将HTML数据写到XML文档中去。我们已经知道该如何创建和存储XML文档。将一个表单数
据写到XML文档中去的过程，现在已演变成为Request Object"s Form Collection以及将每一个表单域的value书定到XML
element value 中去的步骤重复。以上可以通过ASP来完成。
例：将数据输送到XML
现在，我们举一个普通的HTML表单的例子来说明。此Form有用户名，地址，电话，以及E-MAIL等几个域。并将这些信
息写入XML文件中并保存。
EnterContact.html:
1<html>
2<head>
3<title>
4Contact Information
5</title>
6</head>
7<body>
8<form action="processForm.asp" method="post">
9<h3>请输入你的联系方式</h3>
10First Name: <input id="firstName" name="firstName" type="text"/><br/>
11Last Name: <input id="lastName" name="lastName" type="text"/><br/>
12Address #1: <input id="address1" name="address1" type="text"/><br/>
13Address #2: <input id="address2" name="address2" type="text"/><br/>
14Phone Number: <input id="phone" name="phone" type="text"/><br/>
15E-Mail: <input id="email" name="email" type="text"/><br/>
16<input id="btnSub" name="btnSub" type="submit" value="Submit"/><br/>
17</form>
18</body>
19</html>
将Form 中数据发送到processForm.asp.。这是一个ASP页面，在这个ASP中将反复调用同一个函数将form数据写入XML
文件。
