   </products>
</mywebstore>

Any suggestions?? I really need to solve this out!
Thanks Mike

look at
...Libraries\Nop.Services\Seo\SitemapGenerator.cs


        private void WriteProducts()
        {
            var products = _productService.GetAllProducts(false);
            foreach (var product in products)
            {
                //TODO add a method for getting URL (use routing because it handles all SEO friendly URLs)
                var url = string.Format("{0}p/{1}/{2}", _webHelper.GetStoreLocation(false), product.Id, product.GetSeName());
                var updateFrequency = UpdateFrequency.Weekly;
                var updateTime = product.UpdatedOnUtc;
                WriteUrlLocation(url, updateFrequency, updateTime);
            }
        }
