XML is a platform independent language, so if we create an XML file in one platform it can be used in other platforms also.For creating a new XML file in VB.NET, we are using XmlTextWriter class. The class takes FileName and Encoding as arguments. Also we are here passing formating details. The following source code creating an XML file product.xml and add four rows in the file.

Imports System.Xml
Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim writer As New XmlTextWriter("product.xml", System.Text.Encoding.UTF8)
        writer.WriteStartDocument(True)
        writer.Formatting = Formatting.Indented
        writer.Indentation = 2
        writer.WriteStartElement("Table")
        createNode(1, "Product 1", "1000", writer)
        createNode(2, "Product 2", "2000", writer)
        createNode(3, "Product 3", "3000", writer)
        createNode(4, "Product 4", "4000", writer)
        writer.WriteEndElement()
        writer.WriteEndDocument()
        writer.Close()
    End Sub
    Private Sub createNode(ByVal pID As String, ByVal pName As String, ByVal pPrice As String, ByVal writer As XmlTextWriter)
        writer.WriteStartElement("Product")
        writer.WriteStartElement("Product_id")
        writer.WriteString(pID)
        writer.WriteEndElement()
        writer.WriteStartElement("Product_name")
        writer.WriteString(pName)
        writer.WriteEndElement()
        writer.WriteStartElement("Product_price")
        writer.WriteString(pPrice)
        writer.WriteEndElement()
        writer.WriteEndElement()
    End Sub
End Class

Output of the above source code:
