In this article I’m going to explain how to insert delete update records in XML file using ASP.NET and C#.

What is XML?

XML was created to structure, store and transport data.

XML stands for EXtensible Markup Language
XML is a markup language much like HTML
XML was designed to carry data, not to display data
XML tags are not predefined. You must define your own tags
XML is designed to be self-descriptive
XML is a W3C Recommendation

In this article I’ll show you how to insert delete update records in lightweight XML file.

So first we should create XML file

This is sample xml data structure we have created for the demo

<?xml version="1.0" standalone="yes"?>

<name>Sachin</name>

<designation>Software Engineer</designation>

<city>Chennai</city>

<country>India</country>

</Employee>

<name>Suresh</name>

<designation>Web Developer</designation>

<city>New Delhi</city>

<country>India</country>

</Employee>

</EmployeeDetails>
