我有一些XML值,我想將它分配給一個類,我想知道是否可以遍歷類的某些元素(而不是創建類中的數組)。VBA - 爲某個類的某些元素賦值

所以參照下面的XML片段,我想有類設置爲從XML傳遞值如下:

event.homeTeamName 
event.awayTeamName 
event.homeSpread1 
event.homeSpread2 
event.homeSpread3 
event.homeSpread4 
event.homeSpread5 
event.totalPoints1 
event.totalPoints2 
event.totalPoints3 
event.totalPoints4 
event.totalPoints5 

,而不是

event.homeTeamName 
event.awayTeamName 
event.homeSpread(1) 
event.homeSpread(2) 
event.homeSpread(3) 
event.homeSpread(4) 
event.homeSpread(5) 
event.totalPoints(1) 
event.totalPoints(2) 
event.totalPoints(3) 
event.totalPoints(4) 
event.totalPoints(5) 

是有一種方法來循環通過homeSpread1 - homeSpread5 and totalPoints1 - totalPoints5從XML分配值時類的元素?我知道屬性獲取屬性讓功能在類模塊內,但據我所見,這將導致不需要的類涉及數組。另外就我所見,我需要爲每個數組創建一個Property Let/Get

下面是XML片斷的例子:

      <homeTeam type="Team1"> 
           <name>Brisbane Roar</name> 
           <rotNum>2151</rotNum> 
          </homeTeam> 
          <awayTeam type="Team2"> 
           <name>Adelaide United</name> 
           <rotNum>2152</rotNum> 
          </awayTeam> 
          <periods> 
           <period lineId="234921091"> 
            <spreads>

              <awayPrice>2.01</awayPrice> 
              <homeSpread>-0.25</homeSpread> 
              <homePrice>1.909</homePrice>

如果這就是你想要做的,那麼你可以做到這一點。目前尚不清楚究竟是什麼阻止了你? –

這是我的問題 - 我想知道如何遍歷類的某些元素,其中的元素不是特定的數組 – brebbles

這通常是爲什麼這種類型的任務會使用數組:這樣做會讓你的生活變得更加困難。在你的情況下,答案可能是使用'CallByName' –

例子:

Sub Tester() 

    Dim t As New clsTest 
    Dim i As Long 

    For i = 1 To 3 
     CallByName t, "Total" & i, VbLet, i * 10 
    Next i 

    Debug.Print t.Total1, t.Total2, t.Total3 '--> 10, 20, 30 

End Sub 

另clsTest:

Option Explicit 

Private mT1 As Double 
Private mT2 As Double 
Private mT3 As Double 

Property Let Total1(v As Double) 
    mT1 = v 
End Property 
Property Get Total1() As Double 
    Total1 = mT1 
End Property 
Property Let Total2(v As Double) 
    mT2 = v 
End Property 
Property Get Total2() As Double 
    Total2 = mT2 
End Property 
Property Let Total3(v As Double) 
    mT3 = v 
End Property 
Property Get Total3() As Double 
    Total3 = mT3 
End Property 

你也可以簡單地使用公共變量clsTest(無需for getter/setter)

非常感謝,這正是我所追求的。我注意到,當遵循get/set方法時,「v」數組會創建重複條目,因此它會創建mT1/2/3以及Total1/2/3,但這應該很容易處理。 – brebbles

mT1等是用於支持公共屬性Total1等的私有變量,這通常是您實現屬性的方式 - 需要在某個地方將值存儲在類中。 –
