T4 Template Using XML

In this article we learn what a Text Template Transformation Toolkit (T4) template is using XML. If you are unfamiliar with the T4 template then please read my article What a T4 Template is in MVC.

Let's create an empty MVC4 project.

1. Go to File → Project.
   
2. Select ASP.NET MVC 4 Web Application and name it T4TemplateUsingXml.
   
   
   
3. Click Ok.
   
4. Select an Empty Project.

After creating the project let's add a folder called Xml in the root directory.

Right-click on the Xml folder and add a XML file and name it Employee.xml.

After creating Employee.xml paste in the following code. 

1. <Employee>  
2.    
3.      <EmployeeDetail>  
4.          <Id>E001</Id>  
5.          <Name>Pramod</Name>  
6.          <Email>Pramod@yahoo.com</Email>  
7.      </EmployeeDetail>  
8.    
9.      <EmployeeDetail>  
10.          <Id>E002</Id>  
11.          <Name>Ravi Kant</Name>  
12.          <Email>Ravi@yahoo.com</Email>  
13.      </EmployeeDetail>  
14.    
15.      <EmployeeDetail>  
16.          <Id>E003</Id>  
17.          <Name>Rahul</Name>  
18.          <Email>Rahul@yahoo.com</Email>  
19.      </EmployeeDetail>  
20.    
21.      <EmployeeDetail>  
22.          <Id>E004</Id>  
23.          <Name>Deepak</Name>  
24.          <Email>Deepak@yahoo.com</Email>  
25.      </EmployeeDetail>  
26.    
27.  </Employee>  

 To create a model right-click on the Models folder and add a class and name it Employee and paste in the following code: 

1.  using System;  
2.  using System.Xml.Serialization;  
3.  namespace T4TemplateUsingXml.Models  
4.  {  
5.      [Serializable]  
6.      [XmlRoot("Employee"), XmlType("Employee")]  
7.      public class Employee  
8.      {  
9.          public string Id { get; set; }  
10.          public string Name { get; set; }  
11.          public string Email { get; set; }  
12.      }  
13.  }  

 Now we create a controller, right-click on the Controller folder and add a controller named HomeController.

And then right-click on the index code inline and choose Add View using a scaffold empty template.

Let's run the project and see the output.

                                                   

Now I make a copy of List.tt and name it PramodList.tt and make some changes. After that add another view called IndexXml using a scaffold PramodList template.

//Location of List.tt is C:\Program Files\Microsoft Visual Studio 11.0\Common7\IDE\ItemTemplates\CSharp\Web\MVC 4\CodeTemplates\AddView\CSHTML



And write some code in HomeController as in the following:

1. public ActionResult IndexXml()  
2.  {  
3.      string Data = Server.MapPath("~/Xml/Employee.xml");  
4.      DataSet ds = new DataSet();  
5.      ds.ReadXml(Data);  
6.      var employee = new List<Employee>();  
7.      employee = (from item in ds.Tables[0].AsEnumerable()  
8.      select new Employee  
9.      {  
10.          Id = item[0].ToString(),  
11.          Name = item[1].ToString(),  
12.          Email = item[2].ToString(),  
13.      }  
14.      ).ToList();  
15.      return View(employee);  
16.  }  
17.    

And run the application.
