使用宏组合多个xml文件时重复的列

Question

我已经使用了在线提供的代码来将多个xml文件组合成一个Excel。它工作正常，但重复了列。有人可以帮助我，如何在合并xml文件时消除重复。请找到附带的代码。

Sub From_XML_To_XL()
'UpdatebyKutoolsforExcel20151214
    Dim xWb As Workbook
    Dim xSWb As Workbook
    Dim xStrPath As String
    Dim xFileDialog As FileDialog
    Dim xFile As String
    Dim xCount As Long
    On Error GoTo ErrHandler
    Set xFileDialog = Application.FileDialog(msoFileDialogFolderPicker)
    xFileDialog.AllowMultiSelect = False
    xFileDialog.Title = "Select a folder [Kutools for Excel]"
    If xFileDialog.Show = -1 Then
        xStrPath = xFileDialog.SelectedItems(1)
    End If
    If xStrPath = "" Then Exit Sub
    Application.ScreenUpdating = False
    Set xSWb = ThisWorkbook
    xCount = 1
    xFile = Dir(xStrPath & "\*.xml")
    Do While xFile <> ""
        Set xWb = Workbooks.OpenXML(xStrPath & "\" & xFile)
        xWb.Sheets(1).UsedRange.Copy xSWb.Sheets(1).Cells(xCount, 1)
        xWb.Close False
        xCount = xSWb.Sheets(1).UsedRange.Rows.Count + 2
        xFile = Dir()
    Loop
    Application.ScreenUpdating = True
    xSWb.Save
    Exit Sub
ErrHandler:
    MsgBox "no files xml", , "Kutools for Excel"
End Sub
