Hello：）

I think you should use LINQ-TO-XML to deal with the problem by using Descedants to find out the specific element of xsd and then do outputting like following this：

【Sample & Solution】

namespace CSharp
{
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Xml.Linq;

    namespace ConsoleApplication7
    {
        public class Program
        {
            static void Main(string[] args)
            {
                var result = from e in XDocument.Load("XMLFile1.xml").Descendants(XNamespace.Get("http://www.w3.org/2001/XMLSchema") + "complexType")
                             where e.Attribute("name").Value.Equals("EXP")
                             select e.Descendants(XNamespace.Get("http://www.w3.org/2001/XMLSchema") + "element");

                //Loop out all the ComplexType
                foreach (var item in result)
                {
                    //Loop out all the element type nested in the Complex type
                    foreach (var sitem in item)
                    {
                        Console.WriteLine(sitem.Attribute("name").Value);
                    }
                }
                            
            }
        }

    }
}
