I have a DataSetToXml() method which does this:

        ' Convert a DataSet into an Xml
        ' This functions make it so the schema is included
        ' expO1 DataSet
        Public Function DataSetToXml(ByVal toDataSet As DataSet) As String
            Dim loStringWriter As StringWriter = New StringWriter()

            ' Adjust the dataset to avoid null values
            toDataSet = AdjustDataSetToAvoidNullValue(toDataSet)

            toDataSet.WriteXml(loStringWriter, XmlWriteMode.WriteSchema)
            Return loStringWriter.ToString
        End Function

However, once everything is in Xml, for those empty fields, I would like them to be trimmed. Because, in the Xml, this is what I would like to have:

<NewDataSet>
   <Temp>
      <MyField />
   </Temp>
</NewDataSet>

instead of:

<NewDataSet>
   <Temp>
      <MyField> </MyField>
   </Temp>
</NewDataSet>

How can I do that?
