MVC creates XML and implements addition, deletion, and modification.

If you create the following XML:

<?xml version="1.0" encoding="utf-8" standalone="yes"?><Students>  <Student Id="1">    <Name>darren</Name>  </Student></Students>

 

Create an XML file

In HomeController, create the new. xml file in the root directory:

public ActionResult Index()        {            return View();        }        [HttpPost]        public ActionResult AddXml()        {            string path = Server.MapPath("~/new.xml");            XDocument doc = new XDocument(                    new XDeclaration("1.0","utf-8","yes"),                    new XElement("Students",new XElement("Student",                            new XAttribute("Id","1"),                            new XElement("Name","darren")                        ))                );            doc.Save(path);            return Json(new {msg = true}, JsonRequestBehavior.AllowGet);        }

 

Use asynchronous requests in Index. cshtml:

@ Model IEnumerable <MvcApplication1.Models. Student> @ {ViewBag. Title = "Index"; Layout = "~ /Views/Shared/_ Layout. cshtml ";} 



Show XML file elements
Modify the Index method in HomeController as follows:

public ActionResult Index()        {            string path = Server.MapPath("~/new.xml");            List<Student> result = new List<Student>();            var nodes = ReadXML(path).Descendants("Student");            foreach (var node in nodes)            {                Student student = new Student();                student.Id = Convert.ToInt32(node.Attribute("Id").Value);                foreach (var ele in node.Elements())                {                    student.Name = ele.Value;                }                result.Add(student);            }            return View(result);        }        private XDocument ReadXML(string path)        {            XDocument xDoc = new XDocument();            xDoc = XDocument.Load(path);            return xDoc;        }



Modify Home/Index. cshtml:

@ Model IEnumerable <MvcApplication1.Models. Student> @ {ViewBag. Title = "Index"; Layout = "~ /Views/Shared/_ Layout. cshtml ";} 
 
Add element to XML file
HomeController:
public ActionResult Create()        {            return View();        }        [HttpPost]        public ActionResult Create(Student student)        {            string path = Server.MapPath("~/new.xml");            XDocument xd = XDocument.Load(path);            XElement newStudent = new XElement("Student",                new XAttribute("Id", student.Id),                new XElement("Name",student.Name));            xd.Root.Add(newStudent);            xd.Save(path);            return RedirectToAction("Index");        }
 
In Home/Create. csthml:
@ Model MvcApplication1.Models. Student @ {ViewBag. Title = "Create"; Layout = "~ /Views/Shared/_ Layout. cshtml ";}< h2> Create 
 
Modify elements in an XML file
HomeController:
public ActionResult Update(string id)        {            string path = Server.MapPath("~/new.xml");            XElement xe = XElement.Load(path);            var studentXe = xe.Elements("Student").Where(e => e.Attribute("Id").Value == id).FirstOrDefault();            Student student = new Student();            student.Id = Convert.ToInt32(studentXe.Attribute("Id").Value);            student.Name = studentXe.Element("Name").Value;            return View(student);        }        [HttpPost]        public ActionResult Update(Student student)        {            string path = Server.MapPath("~/new.xml");            var studentId = student.Id.ToString();            XDocument xd = XDocument.Load(path);            XElement node =                xd.Root.Elements("Student").Where(e => e.Attribute("Id").Value == studentId).FirstOrDefault();            node.SetElementValue("Name", student.Name);            xd.Save(path);            return RedirectToAction("Index");        }
 
In Home/Update. csthml:
@ Model MvcApplication1.Models. Student @ {ViewBag. Title = "Update"; Layout = "~ /Views/Shared/_ Layout. cshtml ";}< h2> Update 
 
Delete elements in an XML file
HomeController:
public ActionResult Delete(string id)        {            string path = Server.MapPath("~/new.xml");            XElement xe = XElement.Load(path);            var studentXe = xe.Elements("Student").Where(e => e.Attribute("Id").Value == id).FirstOrDefault();            Student student = new Student();            student.Id = Convert.ToInt32(studentXe.Attribute("Id").Value);            student.Name = studentXe.Element("Name").Value;            return View(student);        }        [HttpPost]        public ActionResult Delete(Student student)        {            string path = Server.MapPath("~/new.xml");            var studentId = student.Id.ToString();            XDocument xd = XDocument.Load(path);            xd.Root.Elements("Student").Where(e => e.Attribute("Id").Value == studentId).Remove();            xd.Save(path);            return RedirectToAction("Index");        }
 
In Home/Delete. cshtml:
@ Model MvcApplication1.Models. Student @ {ViewBag. Title = "Delete"; Layout = "~ /Views/Shared/_ Layout. cshtml ";}< h2> Delete
