Help wityh using multyiple values in code using VB.NET

Hi,

I'm using the code below to delete records in other xml files based on record deleted from a datagrid, how I modify the code to apply to multiple countries, for example if I include countries in s = ('BEL', 'FRA', NLD, USA) , How do I loop through the variable and replace country in the code if the file exist (i.e.LinkItemUSA.xml) ?

   For i = Me.C1TrueDBGrid4.SelectedRows.Count - 1 To 0 Step -1
                    Dim DVa As New DataView(dtb, "Child_Item_ID like " & "'" & C1TrueDBGrid4.Columns(0).Value & "'" & " or Parent_Item_ID like " & "'" & C1TrueDBGrid4.Columns(0).Value & "'" & "", Nothing, DataViewRowState.CurrentRows)
                    For X = DVa.Count - 1 To 0 Step -1
                        DVa.Item(X).Delete()
                    Next
                    Dim DV1 As New DataView(dtb, "", Nothing, DataViewRowState.CurrentRows)
                    Dim FilteredDT As DataTable
                    FilteredDT = DV1.ToTable
                    FilteredDT.TableName = "Row"
                    FilteredDT.WriteXml(Application.StartupPath + "\Data\LinkFiles\LinkItemUSA.xml")

                    Dim DVa1 As New DataView(dtc, "Item_ID like " & "'" & C1TrueDBGrid4.Columns(0).Value & "'" & "", Nothing, DataViewRowState.CurrentRows)
                    For X = DVa1.Count - 1 To 0 Step -1
                        DVa1.Item(X).Delete()
                    Next
                    Dim DV11 As New DataView(dtc, "", Nothing, DataViewRowState.CurrentRows)
                    Dim FilteredDT1 As DataTable
                    FilteredDT1 = DV11.ToTable
                    FilteredDT1.TableName = "Row"
                    FilteredDT1.WriteXml(Application.StartupPath + "\Data\LinkFiles\LinkPPFUSA.xml")
