When the form loads, the program creates an XML document (that code is omitted below).
Next the program displays the the document's OuterXml. This is not formatted.
The code then creates a StringWriter to hold the formatted XML document. It creates an XmlTextWriter attached to the StringWriter, sets its Formatting property to indicate we want an indented format, and then writes the XML document into it. It finishes by displaying the resulting string.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal _
e As System.EventArgs) Handles MyBase.Load
Dim doc As New XmlDocument()
doc.LoadXml("...")
txtOuterXml.Text = doc.OuterXml
txtOuterXml.Select(0, 0)
' Use an XmlTextWriter to format.
' Make a StringWriter to hold the result.
Using sw As New System.IO.StringWriter()
' Make the XmlTextWriter to format the XML.
Using xml_writer As New XmlTextWriter(sw)
xml_writer.Formatting = Formatting.Indented
doc.WriteTo(xml_writer)
xml_writer.Flush()
' Display the result.
txtFormatted.Text = sw.ToString()
End Using
End Using
txtFormatted.Select(0, 0)
End Sub
