XML formats differ in "text view"

I am generating a code which is same as generated by "Schneider app" but the problem:
my XML code is differ than their XML code.
if i opened my xml code with text editor it comes different "less spaces before the view"..
 
the problem that i can't import my file to their side.
but if i change my file format to .xml ,i can import it.
so my question how to get the same xml format in text editor and why they have extra spaces in their "text view".
 
i'm writing xml with the below
 

Dim saveFile As New SaveFileDialog()
  saveFile.InitialDirectory = "Desktop"
  saveFile.FileName = fb.Text
  saveFile.Filter = "XML Files Only(*.XML) | *.XML"
  saveFile.ShowDialog()
 
  Dim doc As XmlDocument = New XmlDocument()
  doc.LoadXml(GenCodeText.Text)
  doc.PreserveWhitespace = false
  doc.Save(saveFile.FileName)

 
below is my generated code and their generated code.
