Change XML element sequence

Can anyone help me please..
I am using vb.net to WriteXML from Ms Access tables to an
output stream. Basically, I retrieve data from
3 tables then use DataRelations to link these three
tables, set the Nested property of these DataRelations to
True
so that in the the output XML document, the child node
would be nested within the parent node.

Dim DS as DataSet
Dim Relation_1 As DataRelation = DS.Relations.Add
("Relation_1",
DS.Tables("Table_1").Columns("ID_1"),
DS.Tables("Table_2").Columns("ID_1"))
Relation_1.Nested = True

Dim Relation_2 As DataRelation = DS.Relations.Add
("Relation_2",
DS.Tables("Table_2").Columns("ID_2"),
DS.Tables("Table_3").Columns("ID_2"))
Relation_2.Nested = True

Dim filename As String = "c:\XmlFile.xml"
Dim xmlSW As StreamWriter = New StreamWriter(filename,
True)

DS.WriteXml(xmlSW)

By default, the XML document will display one table
after another, i.e. the second table would be
displayed at the end of the first table & so on.

(1) <Table_1>
(2) <Table_1.Column(0)>
(3) <ID_1>
(4) <Table_1.Column(2)>
(5) <Table_1.Column(3)>
(6) <Table_2>
(7) <ID_1>
(8) <Table_2.Column(1)>
(9) <ID_2>
(10) <Table_2.Column(3)>
(11) </Table_2>
(12) <Table_3>
(13) <ID_2>
(14) <Table_3.Column(1)>
(15) <Table_3.Column(2)>
(16) </Table_3>
(17) </Table_1>


But I need the second table to be displayed where the ID
links.
I.e. Instead of <Table_2> node displayed at line(6), I
need the entire <Table_2> node displays at line (3).
Instead of <Table_3> node displayed at line(12), I need
the entire <Table_3> node displays at line (9).
I also need to hide all the LinkID, i.e. <ID_1>,
<ID_2>.

It should look something like this:

(1) <Table_1>
(2) <Table_1.Column(0)>
(6) <Table_2>
(8) <Table_2.Column(1)>
(12) <Table_3>
(14) <Table_3.Column(1)>
(15) <Table_3.Column(2)>
(16) </Table_3>
(10) <Table_2.Column(3)>
(11) </Table_2>
(4) <Table_1.Column(2)>
(5) <Table_1.Column(3)>
(17) </Table_1>


Does anyone know how to achieve this? Please help me..
thanks.
