How do I save updates in a GridView control in VB to an existing XML document?
I have an existing xml document with music playlist information, which is read into a GridView control in Visual Basic. I am now wanting to save any updates in the GridView to that xml document. How can I do this?

    Private Sub cboUsers_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboUsers.SelectedIndexChanged
        Dim songList As New XmlDocument
        songList.LoadXml(s.GetPlaylist(cboUsers.SelectedItem.ToString())) ' Calls SOAP function, sends parameter username
        Grid.Rows.Clear()
        Dim songs As XmlNodeList = songList.DocumentElement.SelectNodes("//Song") ' Gets all song with single playlist
        Dim song As XmlNode
        For Each song In songs
            Dim artist As String = song.SelectSingleNode("artist").InnerText ' For each song get artist data etc.
            Dim title As String = song.SelectSingleNode("title").InnerText
            Dim length As String = song.SelectSingleNode("length").InnerText
            Dim album As String = song.SelectSingleNode("album").InnerText
            Dim popularity As String = song.SelectSingleNode("popularity").InnerText
            Dim row() As Object = {artist, title, length, album, popularity} ' Put data into an array object
            Grid.Rows.Add(row) ' Add as a row in the Grid
        Next
    End Sub

Thanks
