四、操作Xml数据的Cls_Person类说明（clsPerson.asp）
Cls_Person类用来完成与联系人信息相关的各种操作，包括添加、修改和删除等等，它使用VBScript编写。Cls_Person包括Id、Name、Nick、Mobile、Tel、Email、QQ和Company属性，对应于XML文件中的Person节点。Cls_Person包括GetInfoFromXml、AddToXml、EditToXml和DeleteFormXml四个主要方法，分别完成获取信息，添加信息，修改信息和删除信息四个功能。
Cls_Person的具体实现如下，

五、程序首页（default.asp）
调用相应的包含文件和公共函数，格式化XML文件，并进行显示。可以看到，页面Title是可定制的，公共的头部和尾部都做成了相应的包含文件。C_TITLE、C_XMLFILE和C_XSLFILE为公共常量，在constpub.asp文件中定义，至于它们的意义，相信读者可以很容易地明白。这里调用了上面定义的FormatXml函数。
＜% Option Explicit

六、添加、修改和删除XML中的信息
我们知道，在Cls_Person中已经定义了相应的方法，因此，在各个文件中，只需要调用对应的方法即可。添加信息的文件为add.asp，修改信息的文件为edit.asp，删除信息的文件为delete.asp，我们仅以add.asp文件为例进行说明。其中的CheckStrInput和CheckStrOutput函数，用来格式化用户的输入和输出字符串。
