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。
