Вот решение с использованием XML Linq.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XDocument doc = XDocument.Load(FILENAME);

            XElement UUID = doc.Descendants().Where(x => x.Name.LocalName == "UUID").FirstOrDefault();

            UUID.SetValue("new value");
        }
    }
}
