Hi,

I'm using the code below to convert data in xml file in Part A format.
How do I modify the code to work when Receiver_ID has multiple values? For example if
Receiver_ID is 1,2, I need to transfer 1,2 to BEL,CAN  since in the country's xml file 1 pertains to BEL and 2 pertains to CAN.

Code:

  Dim dt2 As New DataTable("Country")
  dt2.Columns.Add("Link_ID")
  dt2.Columns.Add("Receiver")

  Dim linker2 As XElement = XElement.Load(Application.StartupPath + "\LinkFiles\LinkCountry" & Trim(LoginForm1.username.Text) & ".xml")

 Dim receiver2 As XElement = XElement.Load(Application.StartupPath + "\Receiver.xml")
       

For Each item As XElement In linker2.Elements("Country")
            Dim linkID As String = item.Element("Link_ID").Value
            Dim receiverId As String = item.Element("Receiver_ID").Value

            Dim receiverVal As String = String.Empty
            xe = receiver2.Elements("Row").Cast(Of XElement)().Where(Function(n) n.Element("Receiver_ID").Value = receiverId).FirstOrDefault()
            If xe IsNot Nothing Then
                receiverVal = xe.Element("Receiver").Value
            End If
   Dim dr As DataRow = dt2.NewRow()
            dr("Link_ID") = linkID
            dr("Receiver") = receiverVal
            dt2.Rows.Add(dr)
        Next

        dt2.WriteXml(Application.StartupPath + "\LinkFiles\LinkCountryMain" & Trim(LoginForm1.username.Text) & ".xml")
        '***

Part A

<?xml version="1.0" standalone="yes"?>
<DocumentElement>
  <Country>
    <Link_ID>1</Link_ID>
    <Receiver_ID>1</Receiver_ID>
    <C_ID>1</C_ID>
  </Country>
  <Country>
    <Link_ID>2</Link_ID>
    <Receiver_ID>2</Receiver_ID>
    <C_ID>2</C_ID>
  </Country>
</DocumentElement>

Part B

<?xml version="1.0" standalone="yes"?>
<DocumentElement>
  <Country>
    <Link_ID>1</Link_ID>
    <Receiver_ID>1,2</Receiver_ID>
    <C_ID>1</C_ID>
  </Country>
  <Country>
    <Link_ID>2</Link_ID>
    <Receiver_ID>2</Receiver_ID>
    <C_ID>2</C_ID>
  </Country>
  </DocumentElement>

Thanks,

Victor

Try this:
        For Each item As XElement In linker2.Elements("Country")
            Dim linkID As String = item.Element("Link_ID").Value

            Dim receiverVal As String = String.Empty
            For Each receiverIdSplit As String In item.Element("Receiver_ID").Value.Split({","c})
                Dim receiverId As String = receiverIdSplit
                xe = receiver2.Elements("Row").Cast(Of XElement)().Where(Function(n) n.Element("Receiver_ID").Value = receiverId).FirstOrDefault()
                If xe IsNot Nothing Then
                    If Not receiverVal.Equals(String.Empty) Then receiverVal &= ","
                    receiverVal &= xe.Element("Receiver").Value
                End If
            Next
            Dim dr As DataRow = dt2.NewRow()
            dr("Link_ID") = linkID
            dr("Receiver") = receiverVal
            dt2.Rows.Add(dr)
        Next
