如何选择当前节点的所有子节点？

  XmlNodeList productNodes = doc.DocumentElement.SelectNodes("//PRODUCT");
        Parallel.ForEach(productNodes.Cast<XmlNode>(),
                         (XmlNode productNode) =>
                         {
                             string _productMode = XmlUtils.nodeAsString(productNode, "@mode");
                             Product product = new Product()
                             {
                                 Mode = XmlUtils.nodeAsString(productNode, "@mode"),
                                 No = XmlUtils.nodeAsString(productNode, "./SUPPLIER_PID"),
                                 DescriptionShort = XmlUtils.nodeAsString(productNode, "./PRODUCT_DETAILS/DESCRIPTION_SHORT"),
                                 DescriptionLong = XmlUtils.nodeAsString(productNode, "./PRODUCT_DETAILS/DESCRIPTION_LONG"),
                                 EANCode = XmlUtils.nodeAsString(productNode, "./PRODUCT_DETAILS/EAN"),
                                 Stock = XmlUtils.nodeAsInt(productNode, "./PRODUCT_DETAILS/STOCK"),
                                 OrderUnit = default(QuantityCodes).FromString(XmlUtils.nodeAsString(productNode, "./PRODUCT_ORDER_DETAILS/ORDER_UNIT")),
                                 ContentUnit = default(QuantityCodes).FromString(XmlUtils.nodeAsString(productNode, "./PRODUCT_ORDER_DETAILS/CONTENT_UNIT")),
                                 Currency = default(CurrencyCodes).FromString(XmlUtils.nodeAsString(productNode, "./PRODUCT_PRICE_DETAILS/PRODUCT_PRICE/PRICE_CURRENCY")),
                                 VAT = XmlUtils.nodeAsInt(productNode, "./PRODUCT_PRICE_DETAILS/PRODUCT_PRICE/TAX"),
                             };
                             XmlNodeList MimeNodes = doc.DocumentElement.SelectNodes(".//MIME");

                             Parallel.ForEach(MimeNodes.Cast<XmlNode>(), (XmlNode MimeNode) =>
                             {
                                 Mime mime = new Mime()
                                 {
                                     Source = XmlUtils.nodeAsString(MimeNode, "./MIME_SOURCE"),
                                     Type = XmlUtils.nodeAsString(MimeNode, "./MIME_TYPE"),
                                     Purpose = XmlUtils.nodeAsString(MimeNode, "./MIME_PURPOSE")
                                 };
                                 product.Mime.Add(mime);
                             });......
<PRODUCT mode="new">

        <PRODUCT_DETAILS>
            <DESCRIPTION_SHORT>NORDEN Table</DESCRIPTION_SHORT>
            <DESCRIPTION_LONG>massive birch wood. 135x74cm, 74 cm height by Mikael Warnhammar</DESCRIPTION_LONG>

                <PRICE_CURRENCY>EUR</PRICE_CURRENCY>
                <LOWER_BOUND>200</LOWER_BOUND>
                <TERRITORY>AT</TERRITORY>
            </PRODUCT_PRICE>
        </PRODUCT_PRICE_DETAILS>
        <MIME>
            <MIME_SOURCE>http://www.google.de/</MIME_SOURCE>
            <MIME_TYPE>text/html</MIME_TYPE>
            <MIME_PURPOSE>url</MIME_PURPOSE>
        </MIME>
        <MIME>
            <MIME_SOURCE>http://www.stackoverflow.com</MIME_SOURCE>
            <MIME_TYPE>text/html</MIME_TYPE>
            <MIME_PURPOSE>url</MIME_PURPOSE>
        </MIME>
    </PRODUCT>

实际上我得到了所有产品节点，我试图获取每个产品节点的所有mimes子节点来保存它..但是当我这样做时，我重复了mime节点。

我不太了解xpath可能是因为我需要speficy祖先节点？我尝试使用后代，但我得到了相同的结果。

尝试使用Xml Linq解决方案

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);
            List<XElement> productNodes = doc.Descendants("PRODUCT").ToList();

            List<Product> product = productNodes.Select(x => new Product() {
                Mode = (string)x.Attribute("mode"),
                No = (string)x.Element("SUPPLIER_PID"),
                DescriptionShort = (string)x.Descendants("DESCRIPTION_SHORT").FirstOrDefault(),
                DescriptionLong = (string)x.Descendants("DESCRIPTION_LONG").FirstOrDefault(),
                //EANCode = XmlUtils.nodeAsString(productNode, "./PRODUCT_DETAILS/EAN"),
                //Stock = XmlUtils.nodeAsInt(productNode, "./PRODUCT_DETAILS/STOCK"),
                OrderUnit = (string)x.Descendants("ORDER_UNIT").FirstOrDefault(),
                ContentUnit = (string)x.Descendants("CONTENT_UNIT").FirstOrDefault(),
                Currency =  (string)x.Descendants("PRICE_CURRENCY").FirstOrDefault(),
                mime = x.Elements("MIME").Select(y => new Mime() {
                    Source = (string)y.Element("MIME_SOURCE"),
                    Type = (string)y.Element("MIME_TYPE"),
                    Purpose = (string)y.Element("MIME_PURPOSE")
                }).ToList()
            }).ToList();

        }
    }
    public class Product
    {
        public string Mode  { get; set;}
        public string No  { get; set;}
        public string DescriptionShort  { get; set;}
        public string DescriptionLong  { get; set;}
        public string EANCode  { get; set;}
        public string OrderUnit  { get; set;}
        public string ContentUnit  { get; set;}
        public string Currency  { get; set;}
        public string Vat  { get; set;} 
        public List<Mime> mime { get; set;}
    }
    public class Mime
    {
        public string Source { get; set; }
        public string Type { get; set;}
        public string Purpose { get; set;}

    }
}
