将HTML表单数据存储为XML格式(2),将HTML表单数据存储为XML格式(2)
MyXMLDoc.xml:
<?xml version="1.0"?>
<rootElement>
<childElement1 />
<childElement2 />
</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:
<html>
<head>
<title>
Contact Information
</title>
</head>
<body>
<form action="processForm.asp" method="post">
<h3>请输入你的联系方式</h3>
First Name: <input type="text" id="firstName" name="firstName"><br>
Last Name: <input type="text" id="lastName" name="lastName"><br>
Address #1: <input type="text" id="address1" name="address1"><br>
Address #2: <input type="text" id="address2" name="address2"><br>
Phone Number: <input type="text" id="phone" name="phone"><br>
E-Mail: <input type="text" id="email" name="email"><br>
<input type="submit" id="btnSub" name="btnSub" value="Submit"><br>
</form>
</body>
</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。
processForm.asp:
