還有一個(gè)讀取XML的類(lèi) 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，萬(wàn)事俱備，開(kāi)始搭建基本的三層：
數(shù)據(jù)模型層：此層對(duì)應(yīng)成一個(gè)類(lèi)，類(lèi)的類(lèi)名和字段屬性對(duì)應(yīng)于數(shù)據(jù)庫(kù)的相應(yīng)表名及字段。
考慮表News，其結(jié)構(gòu)如下：


則其對(duì)應(yīng)的模型層如下：
<%
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
%>

這里用了類(lèi)名DataNews，因?yàn)閂BScript不支持Namespace(-_-)，以前綴區(qū)分，而類(lèi)中私有屬性用I作前綴，沒(méi)什么特別含義，僅僅是因?yàn)镮所占寬度較小，不影響理解時(shí)的聯(lián)想反應(yīng)速度，如果非要拉點(diǎn)合理的解釋的話(huà)，那么就是，Private中的I，以區(qū)分于Public，不用m_之類(lèi)，是因?yàn)橛X(jué)得它不夠美觀，影響編碼心情（所以不喜歡寫(xiě)C），因?yàn)樾枰詢(xún)?yōu)雅之心情，編寫(xiě)優(yōu)雅的代碼(哎呀，誰(shuí)扔的雞蛋？拜托換個(gè)新鮮點(diǎn)的）。
