带有命名空间的xml解析，C#

前一段时间做花旗的接口，返回的xml格式是带有命名空间的，可是难倒了我，找了好久才找到解决办法，给大家分享下，少走弯路。

1，直接进入正题，先看一段带有命名空间的xml，这段xml大概的意思是，前面是header信息，后面是body中的信息，body中有不少的节点，主要的是

<ns6:RewardDetail>节点，这个节点包含了很多的<ns8:RedemptionDetails>节点，和一个<ns8:CurrentRewardStatementDetails>节点以及后续以ns8开头的节点。

 2，这一步我们,要开始解析xml，当然准备工作也是要做的，命名空间一定要引用using System.Xml，怎么处理命名空间这一步也将处理。

实例化一个xml命名空间管理器，然后将不同的命名空间加入管理器中，这些命名空间我们从哪里找呢？很显然我们要从xml文档中把他们找出来

xml文档中只要是带有这种 （xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"）的都是命名空间，要把解析时候要用的

命名空间加入命名空间管理器。

XmlDocument doc = new XmlDocument();
doc.LoadXml(“xml字符串”);
XmlNamespaceManager nsMgr = new XmlNamespaceManager(doc.NameTable);//这一步实例化一个xml命名空间管理器
nsMgr.AddNamespace("SOAP-ENV", "http://schemas.xmlsoap.org/soap/envelope/");
nsMgr.AddNamespace("ns", "http://www.citi.com/gcgi/services/common/addressandcontact/v5_5_0_0");
nsMgr.AddNamespace("ns0", "http://www.citi.com/gcgi/shared/system/header");
nsMgr.AddNamespace("ns1", "http://www.citi.com/gcgi/services/common/addressandcontact/v6_0_0_0");
nsMgr.AddNamespace("ns2", "http://www.citi.com/gcgi/entities/common/customer/v5_9_0_0");
nsMgr.AddNamespace("ns3", "http://www.citi.com/gcgi/shared/system/header");
nsMgr.AddNamespace("ns4", "http://www.citi.com/gcgi/shared/system/systemtypes");
nsMgr.AddNamespace("ns5", "http://www.citi.com/gcgi_prov/services/cards/reward/v6_0_0_0");
nsMgr.AddNamespace("ns6", "http://www.citi.com/gcgi/services/cards/reward/v6_0_0_0");
nsMgr.AddNamespace("ns7", "http://www.citi.com/gcgi_prov/entities/cards/reward/v6_0_0_0");
nsMgr.AddNamespace("ns8", "http://www.citi.com/gcgi/entities/cards/reward/v6_0_0_0");

3，为了接收xml中的值，我新建了一个类

public class RedemptionDetails
{
    public string RedemptionNo { get; set; }
    public string RedemptionStatus { get; set; }
    public string RedemptionPoints { get; set; }
    public string RedemptionAmount { get; set; }
    public string RedemptionDescription { get; set; }
    public string CreatorId { get; set; }
    public string RedemptionDate { get; set; }
    public string RedemptionProgram { get; set; }
    public string RedemptionBonusProgram { get; set; }
    public string RedemptionLevel { get; set; }
    public string RedemptionQuantity { get; set; }
}

4，下面的代码是我具体的实现解析到我需要的具体值，这些也不做过多的解释，直接上代码

                    XmlNode ss = doc.SelectSingleNode("SOAP-ENV:Envelope/SOAP-ENV:Body/ns6:RewardDetailInqRs/ns6:Base", nsMgr);
                    if (ss != null)
                    {
                        XmlNode code = ss.SelectSingleNode("ns3:RsHeader/ns3:ResponseCode", nsMgr);
                        detail.ResponseCode = code.InnerText.Split('_')[2] == "0" ? "0000" : code.InnerText.Split('_')[2]; ;

                        XmlNode current = ss.SelectSingleNode("ns6:RewardDetail", nsMgr).SelectSingleNode("ns8:CurrentRewardStatementDetails", nsMgr);
                        string Avaliable = current.SelectSingleNode("ns8:Available", nsMgr).InnerText;
                        detail.Available = ConvertToPoint(Avaliable);
                        string Redeemed = current.SelectSingleNode("ns8:Redeemed", nsMgr).InnerText;
                        detail.Redeemed = ConvertToPoint(Redeemed);
                        XmlNodeList RedemptionDetailsList = ss.SelectSingleNode("ns6:RewardDetail", nsMgr).SelectNodes("ns8:RedemptionDetails", nsMgr);
                        List<RedemptionDetails> ListDetail = new List<RedemptionDetails>();
                        for (int i = 0; i < RedemptionDetailsList.Count; i++)
                        {
                            RedemptionDetails redemptionDetails = new RedemptionDetails();
                            redemptionDetails.RedemptionNo = RedemptionDetailsList[i].SelectSingleNode("ns8:RedemptionNo", nsMgr).InnerText;
                            if (RedemptionDetailsList[i].SelectSingleNode("ns8:RedemptionStatus", nsMgr) != null)
                            {
                                redemptionDetails.RedemptionStatus = RedemptionDetailsList[i].SelectSingleNode("ns8:RedemptionStatus", nsMgr).InnerText;
                            }
                            else
                            {
                                redemptionDetails.RedemptionStatus = "";
                            }
                            string RedemptionPoints = RedemptionDetailsList[i].SelectSingleNode("ns8:RedemptionPoints", nsMgr).InnerText;
                            redemptionDetails.RedemptionPoints = ConvertToPoint(RedemptionPoints);
                            string RedemptionAmount = RedemptionDetailsList[i].SelectSingleNode("ns8:RedemptionAmount", nsMgr).InnerText;
                            redemptionDetails.RedemptionAmount =ConvertToPoint(RedemptionAmount);
                            redemptionDetails.RedemptionDescription = RedemptionDetailsList[i].SelectSingleNode("ns8:RedemptionDescription", nsMgr).InnerText;
                            redemptionDetails.CreatorId = RedemptionDetailsList[i].SelectSingleNode("ns8:CreatorId", nsMgr).InnerText;
                            redemptionDetails.RedemptionDate = RedemptionDetailsList[i].SelectSingleNode("ns8:RedemptionDate", nsMgr).InnerText;
                            redemptionDetails.RedemptionProgram = RedemptionDetailsList[i].SelectSingleNode("ns8:RedemptionMiniDetails/ns8:RedemptionProgram", nsMgr).InnerText;
                            redemptionDetails.RedemptionBonusProgram = RedemptionDetailsList[i].SelectSingleNode("ns8:RedemptionMiniDetails/ns8:RedemptionBonusProgram", nsMgr).InnerText;
                            redemptionDetails.RedemptionLevel = RedemptionDetailsList[i].SelectSingleNode("ns8:RedemptionMiniDetails/ns8:RedemptionLevel", nsMgr).InnerText;
                            redemptionDetails.RedemptionQuantity = RedemptionDetailsList[i].SelectSingleNode("ns8:RedemptionMiniDetails/ns8:RedemptionQuantity", nsMgr).InnerText;
                            ListDetail.Add(redemptionDetails);
                        }
                        detail.ListDetail = ListDetail;
                    }

5，本例子到此结束，没有什么高深的东西，很简单的东西可能之前没用过而已，希望对大家有所帮助，这也是我现实中遇到的问题，和大家分享下。
