帶有命名空間的xml解析，C#

前一段時間做花旗的接口，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。

1，直接進入正題，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中有不少的節點，主要的是

<ns6:RewardDetail>節點，這個節點包含了很多的<ns8:RedemptionDetails>節點，和一個<ns8:CurrentRewardStatementDetails>節點以及后續以ns8開頭的節點。

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">  <SOAP-ENV:Header>    <ns0:RsHeader xmlns:ns0="http://www.citi.com/gcgi/shared/system/header">      <ns0:DateAndTimeStamp>2014-05-29T02:17:07.634-04:00</ns0:DateAndTimeStamp>      <ns0:UUID>55555461</ns0:UUID>      <ns0:ESBUUID>8dc47a89-3e3b-4b17-a631-938b848447ed</ns0:ESBUUID>      <ns0:ResponseCode>EC_6000_0</ns0:ResponseCode>    </ns0:RsHeader>  </SOAP-ENV:Header>  <SOAP-ENV:Body>    <ns6:RewardDetailInqRs xmlns:ns="http://www.citi.com/gcgi/services/common/addressandcontact/v5_5_0_0" xmlns:ns5="http://www.citi.com/gcgi_iption>50 RMB CASH REBATE</ns8:RedemptionDescription>            <ns8:CreatorId>RWBGBD08</ns8:CreatorId>            <ns8:RedemptionDate>2015-02-06</ns8:RedemptionDate>          </ns8:RedemptionDetails>          <ns8:RedemptionDetails>            <ns8:RedemptionNo>99798499299998</ns8:RedemptionNo>            <ns8:RedemptionStatus>F</ns8:RedemptionStatus>            <ns8:RedemptionMiniDetails>              <ns8:RedemptionProgram>1</ns8:RedemptionProgram>              <ns8:RedemptionBonusProgram>0</ns8:RedemptionBonusProgram>              <ns8:RedemptionLevel>00006</ns8:RedemptionLevel>              <ns8:RedemptionQuantity>2480</ns8:RedemptionQuantity>            </ns8:RedemptionMiniDetails>            <ns8:RedemptionPoints>1.24E6</ns8:RedemptionPoints>            <ns8:RedemptionAmount>0.0E0</ns8:RedemptionAmount>            <ns8:RedemptionDescription>50 RMB CASH REBATE</ns8:RedemptionDescription>            <ns8:CreatorId>RWBGBD08</ns8:CreatorId>            <ns8:RedemptionDate>2015-01-07</ns8:RedemptionDate>          </ns8:RedemptionDetails>          <ns8:CurrentRewardStatementDetails>            <ns8:Sales>0.0E0</ns8:Sales>            <ns8:Beginning>9.80000008E10</ns8:Beginning>            <ns8:Earned>0.0E0</ns8:Earned>            <ns8:Bonus>0.0E0</ns8:Bonus>            <ns8:Adjusted>0.0E0</ns8:Adjusted>            <ns8:Redeemed>1.914E5</ns8:Redeemed>            <ns8:Available>9.79998094E10</ns8:Available>          </ns8:CurrentRewardStatementDetails>          <ns8:EnrolProgram>1</ns8:EnrolProgram>          <ns8:Description>YUPPIES</ns8:Description>          <ns8:EnrolmentIndicator>Y</ns8:EnrolmentIndicator>          <ns8:FlagTime>00:00:00</ns8:FlagTime>          <ns8:MembershipStatus>A</ns8:MembershipStatus>        </ns6:RewardDetail>      </ns6:Base>    </ns6:RewardDetailInqRs>  </SOAP-ENV:Body></SOAP-ENV:Envelope>

2，這一步我們,要開始解析xml，當然準備工作也是要做的，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。

實例化一個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

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);//這一步實例化一個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，我新建了一個類

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現解析到我需要的具體值，這些也不做過多的解釋，直接上代碼

                    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.S
