Help with adding Missing Data elements using VB.NET

Hi,

How do you modify the code below to add data element Effect to tables where it's missing the code below only works if all the tables don't contain the Effect data element.


Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        Dim xdoc As XDocument = XDocument.Load(Application.StartupPath + "\AOP5.xml")
        Dim results = (From n In xdoc.Root.Descendants("AOP5")
                       Select n).ToList()
        Dim resultsa = (From n In xdoc.Root.Descendants("Effect")
                    Select n).Count()

        If resultsa = 0 Then
        results.ForEach(Sub(n) n.Add(<Effect></Effect>))
        End If

        xdoc.Save(Application.StartupPath + "\AOP5.xml")

Hi Victor;

Try it like this, it should give what you need.
Private Sub Button1_Click(Sender As System.Object, E As System.EventArgs) Handles Button1.Click

  Dim Xdoc As XDocument = XDocument.Load(Application.StartupPaTh + "\AOP5.Xml")
  
  Dim Results = (From N In Xdoc.Root.Descendants("AOP5")
                 Where N.Element("Effect") Is Nothing
                 Select N).ToList()
  
  Results.ForEach(Sub(N) N.Add(<Effect></Effect>))
  
  
  Xdoc.Save(Application.StarTupPath + "\AOP5.Xml")
