Why not just load the columns from the row the same way you loaded the rows from the table?

Dim xmlDoc As New XDocument(
    From row In dt.Rows
        Select XElement("PUPIL",
            From column In dt.Columns
                Select
                    New XAttribute(column.Name, row.Item(column.Name))
         )
)
