I have done this in normal HTML table but I want this data in Asp table how can I do this?

You can use your xml file as a data source for a gridview for an example:

    DataSet dataSet = new DataSet(); //create an empty dataset
    dataSet.ReadXml(@"C:\somewhere\file.xml"); //fill it with xml file content
    GridView1.DataSource = dataSet.Tables[0]; //first table from dataset to be loaded 
    GridView1.DataBind(); //load the data into gridview
