帶有命名空間的xml解析，C#-創(chuàng)新互聯(lián)

前一段時(shí)間做花旗的接口，返回的xml格式是帶有命名空間的，可是難倒了我，找了好久才找到解決辦法，給大家分享下，少走彎路。帶有命名空間的xml解析，C#

1，直接進(jìn)入正題，先看一段帶有命名空間的xml，這段xml大概的意思是，前面是header信息，后面是body中的信息，body中有不少的節(jié)點(diǎn)，主要的是

 2，這一步我們,要開(kāi)始解析xml，當(dāng)然準(zhǔn)備工作也是要做的，命名空間一定要引用using System.Xml，怎么處理命名空間這一步也將處理。

實(shí)例化一個(gè)xml命名空間管理器，然后將不同的命名空間加入管理器中，這些命名空間我們從哪里找呢？很顯然我們要從xml文檔中把他們找出來(lái)

xml文檔中只要是帶有這種 （xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"）的都是命名空間，要把解析時(shí)候要用的

命名空間加入命名空間管理器。

XmlDocument doc = new XmlDocument();
doc.LoadXml(“xml字符串”);
XmlNamespaceManager nsMgr= new XmlNamespaceManager(doc.NameTable);//這一步實(shí)例化一個(gè)xml命名空間管理器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，為了接收xml中的值，我新建了一個(gè)類(lèi)

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，下面的代碼是我具體的實(shí)現(xiàn)解析到我需要的具體值，這些也不做過(guò)多的解釋?zhuān)苯由洗a

                    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，本例子到此結(jié)束，沒(méi)有什么高深的東西，很簡(jiǎn)單的東西可能之前沒(méi)用過(guò)而已，希望對(duì)大家有所幫助，這也是我現(xiàn)實(shí)中遇到的問(wèn)題，和大家分享下。
