将HTML表单数据存储为XML格式 - 2

关注+2004-11-07作者:蓝点

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:















  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:





<br><BR> Contact Information<br><BR>









请输入你的联系方式



First Name:


Last Name:


Address #1:


Address #2:


Phone Number:


E-Mail:













  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:
