LINQ TO XML, How to replace values with new values c#

Question

Below is my Sample XML File:-

I just want to replace date values with current date using LINQ to XML in C#.

Answer 1

Which date values? All of them? Specific elements? For example, this will replace all displayDateTime elements with the current date - in standard XML format, which isn't what your source XML contains... if you want a different format, you should use DateTime.ToString and replace the contents of the elements with the relevant text.

using System;
using System.Linq;
using System.Xml.Linq;

class Test
{
    static void Main()
    {
        XNamespace ns = "http://www.uk.ssp.com/SSR/XTI/Traffic/0010";
        XDocument doc = XDocument.Load("ssp.xml");

        var elements = doc.Descendants(ns + "displayDateTime")
                          .ToList();

        var today = DateTime.Today;
        foreach (var element in elements)
        {
            element.ReplaceAll(today);
        }
        Console.WriteLine(doc);
    }
}
