Answer 1

You can sort using LINQ to Xml, if XmlDocument is not the case

XDocument input = XDocument.Load(@"input.xml");
XDocument output = new XDocument(
    new XElement("Users",
        from node in input.Root.Elements()
        orderby node.Attribute("Name").Value descending
        select node));
