读取XML的类 XmlReader

【 tulaoshi.com - Web开发 】

　　还有一个读取XML的类 XmlReader：

%
Class XmlReader

Private Xml

Public Sub Load(ByVal Path)
Xml.Load(Server.MapPath(Path))
End Sub

Public Function SelectSingleNode(ByVal XPath)
Set SelectSingleNode = Xml.SelectSingleNode(XPath)
End Function

Public Function SelectNodes(ByVal XPath)
Set SelectNodes = Xml.SelectNodes(XPath)
End Function

Private Sub Class_initialize()
Set Xml = Server.CreateObject("Microsoft.XMLDOM")
Xml.async = False
''Xml.setProperty "ServerHTTPRequest", True
End Sub
Private Sub Class_Terminate()
Set Xml = Nothing
End Sub

End Class
%

　　好了，万事俱备，开始搭建基本的三层：

　　数据模型层：此层对应成一个类，类的类名和字段属性对应于数据库的相应表名及字段。

　　考虑表News，其结构如下：

　　则其对应的模型层如下：

%
Class DataNews

Private IAddDate
Private IContent
Private ICount
Private INewsID
Private ITitle
Private IUserID
Private IUserName

Public Property Let AddDate(ByVal Value)
IAddDate = Value
End Property
Public Property Get AddDate()
AddDate = IAddDate
End Property

Public Property Let Content(ByVal Value)
IContent = Value
End Property
Public Property Get Content()
Content = IContent
End Property

Public Property Let Count(ByVal Value)
ICount = Value
End Property
Public Property Get Count()
Count = ICount
End Property

Public Property Let NewsID(ByVal Value)
INewsID = Value
End Property
Public Property Get NewsID()
NewsID = INewsID
End Property

Public Property Let Title(ByVal Value)
ITitle = Value
End Property
Public Property Get Title()
Title = ITitle
End Property

Public Property Let UserID(ByVal Value)
IUserID = Value
End Property
Public Property Get UserID()
UserID = IUserID
End Property

Public Property Let UserName(ByVal Value)
IUserName = Value
End Property
Public Property Get UserName()
UserName = IUserName
End Property

Private Sub Class_initialize()
End Sub
Private Sub Class_Terminate()
End Sub

End Class
%

　　这里用了类名DataNews，因为VBScript不支持Namespace(-_-)，以前缀区分，而类中私有属性用I作前缀，没什么特别含义，仅仅是因为I所占宽度较小，不影响理解时的联想反应速度，如果非要拉点合理的解释的话，那么就是，Private中的I，以区分于Public，不用m_之类，是因为觉得它不够美观，影响编码心情（所以不喜欢写C），因为需要以优雅之心情，编写优雅的代码(哎呀，谁扔的鸡蛋？拜托换个新鲜点的）。
