Hey Geeks,
Writing xml file in .net application is quit general but I have noticed most of the people do this work in a loong and wrong (in my opinion) way. They write the xml file with the help of dataset which is more like a database...... Yes offcourse resource heavy. So let us make this operation quit simple and easy. consider the following XML Schema. We will write the same schema from our code to a local file.

XML Schema :

xml version="1.0" encoding="utf-8"?>
<Items>
        <Item>
             <ItemId>3ItemId>
             <ProductName>Pine AppleProductName>
              <Price>30 $Price>
        Item>
Items>

VB.net Code :

Dim XMLDoc As New XmlDocument

XMLDoc.Load(Server.MapPath("MyData.xml"))

Dim XEle As XmlElement = XMLDoc.CreateElement("Item")

Dim XTxt As XmlText

'XMLDoc.DocumentElement.AppendChild(XEle)

XEle = XMLDoc.CreateElement("ItemID")

XTxt = XMLDoc.CreateTextNode("3")

XMLDoc.DocumentElement.AppendChild(XEle)

XMLDoc.DocumentElement.LastChild.AppendChild(XTxt)

XEle = XMLDoc.CreateElement("ProductName")

XTxt = XMLDoc.CreateTextNode("Meera")

XMLDoc.DocumentElement.AppendChild(XEle)

XMLDoc.DocumentElement.LastChild.AppendChild(XTxt)

XEle = XMLDoc.CreateElement("Price")

XTxt = XMLDoc.CreateTextNode("50 $")

XMLDoc.DocumentElement.AppendChild(XEle)

XMLDoc.DocumentElement.LastChild.AppendChild(XTxt)

XMLDoc.Save(Server.MapPath("MyData.xml"))
