How to change an xml file elements attributes in vb.net

Question

Hi I have a class Booking that stores booking information, I have to have BOOKING to look like this

Answer 1

Your class would look like this assuming that's all there is to the node (you didn't close it).

Imports System.Xml.Serialization

Class BOOKING
    
    Public Property partner As String
    
    Public Property transaction As String
    
    Public Property version As String
End Class

Usage

Dim s = New XmlSerializer(GetType(BOOKING))

If it's a string in code

Dim xml = ""

Or you can read it from a file

Using sr As New StreamReader("xmlFileNameAndPath.xml")
    xml = sr.ReadToEnd()
End Using

The deserialize into your BOOKING object

Dim b As BOOKING = s.Deserialize(New StringReader(xml))

You can then edit the object and serialize it back to the original xml

b.partner = "different company"
Using sw As New StreamWriter("xmlFileNameAndPath.xml")
    s.Serialize(sw, b)
End Using

Though in a real xml file you would have an XmlRoot element (this solution uses BOOKING as the root) then you would be able to have multiple BOOKING elements inside that. Hope this gets you rolling.
