Problem merge XML documents with whitespace

[nakkii]

Here is my code:

____________________________________________________
Imports System.Xml
Module XMLMerge

Sub MergeXML(ByVal XMLPath As String, ByVal XMLFile1 As String, ByVal XMLFile2 As String, ByVal XMLFile3 As String)

Dim xmlreader1 As New XmlTextReader(XMLPath & XMLFile1)
Dim xmlreader2 As New XmlTextReader(XMLPath & XMLFile2)
Dim xmlreader3 As New XmlTextReader(XMLPath & XMLFile3)

Dim ds1 As New DataSet()
Try
ds1.ReadXml(xmlreader1)

Dim ds2 As New DataSet()
ds2.ReadXml(xmlreader2)

Dim ds3 As New DataSet()
ds3.ReadXml(xmlreader3)

ds1.Merge(ds2)
ds1.Merge(ds3)
ds1.WriteXml(XMLPath & "FinalFile.XML", XmlWriteMode.IgnoreSchema)
Console.WriteLine("Completed merging XML documents&quot
Catch ex As Exception
Console.WriteLine(ex.Message)
End Try
Console.Read()

End Sub

End Module
___________________________________________________

The resulting XML file is read by another application and uses the data to fill out a form. In this XML file are several elements that relate to checkboxes on the form.

XMLFile1:
<?xml version=&quot;1.0&quot; ?>
<Form>
<FormData FieldName=&quot;CheckBox1&quot;>X</FormData>
<FormData FieldName=&quot;CheckBox2&quot;>X</FormData>
<FormData FieldName=&quot;Checkbox3&quot;> </FormData>
</Form>

XMLFile2:
<?xml version=&quot;1.0&quot; ?>
<Form>
<FormData FieldName=&quot;CheckBox4&quot;>X</FormData>
<FormData FieldName=&quot;CheckBox5&quot;> </FormData>
<FormData FieldName=&quot;Checkbox6&quot;>X</FormData>
</Form>

When I merge the documents this is the result:

<?xml version=&quot;1.0&quot; ?>
<Form>
<FormData FieldName=&quot;CheckBox1&quot;>X</FormData>
<FormData FieldName=&quot;CheckBox2&quot;>X</FormData>
<FormData FieldName=&quot;Checkbox3&quot; />
<FormData FieldName=&quot;CheckBox4&quot;>X</FormData>
<FormData FieldName=&quot;CheckBox5&quot; />
<FormData FieldName=&quot;Checkbox6&quot;>X</FormData>
</Form>


I need to preserve the whitespace in the elements in order to clear the checkbox if it is already checked.

I have tried using the { xml:space = &quot;preserve&quot; } Tag


Please Help......
