You can try something along these lines:

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

namespace ConsoleApplication46
{
    class Program
    {
        static void Main(string[] args)
        {
            XDocument xdoc = XDocument.Load("input.xml");
            MemoryStream newStream = new MemoryStream();
            XNamespace i = "http://Navms.Ms.ExternalInterfaces/2011";
            IEnumerable<XElement> searchResults = xdoc.Descendants(i + "SearchResults")
                                                        .Descendants(i + "SearchResults");

            searchResults.First().Save(newStream);
        }
    }
}

Sorry for offtopic, why do you want to get rid of xmlns:i? It's just a declaration of an alias for the namespace, while the element itself does not belong to that namespace, so the declaration does not make your post-processing any harder.

Hi sorry for the delay in replying
Thanks for the above help, I will give it a try later today and update you

As to the offtopic comment:
I am putting the fragment into a datatable which I will then staore to an sql database, this works fine and seems staright forward, but if I try loading the whole documnet into a datatable I get errors, I'm a bit new this and have chosen the path of least resistance!!!

@JustAndrei

Hopefully I'll be corrected if I am wrong ; )

I initially thought he was trying to strip out the alias, but I looked a bit closer and there are actually two SearchResults elements--one a descendant of the other. The ancestor has the namespace declaration whereas the descendant does not. The code above reflects trying to get the descendant, not the ancestor.

Oh, I didn't notice there were two elements, so I thought Puds32 wanted to remove the declaration. Now it seems the descendant is needed indeed. Sorry, it's my mistake.

Btw, kaufmed, I suspect your code may output namespace navms.ms... Doesn't it? (I haven't tried)
I'm asking because Puds32 seems to want to get rid of all namespaces.

Hi kaufmed
Your solution seems to have worked beautifully, the resulting xml fragment loaded into a datatable and that desplayed in a grid

Hi JustAndrei
You right it did include a namespace in the fragment, but this didn't seem to stop it loading into a datatable so I can live with it, if you know how to get rid of the namespace that would be good

Thanks to you both
Regards Puds32

foreach( var e in searchResults.First().DescendantsAndSelf() )
{
    e.Name = XNamespace.None.GetName( e.Name.LocalName );
}
