XML响应处理

我从eBay API调用获取原始XML响应。现在我必须从XML中获取值并将这些值添加到ViewModel对象，然后将数据返回到我的View。我已经尝试了几件事，但我无法获取XML响应项并分配给ViewModel。请检查以下代码的每个部分，并让我知道你是否有任何解决方案。我不需要工作代码因为我知道你不能测试它，因为它未完成。只是简单的提示就够了，但是，我是新的与C＃。非常感谢提前XML响应处理

控制器：

public ActionResult Search(string OperationName, string calltype, string page, string keywords, string type, string location, string condition, string min, string max, string negative, string minFeedback, string maxFeedback, string drange, string categoryId) 
     { 
      string AppId = "KavinHim-BestProd-PRD-785446bf1-666"; //api configs 
      string BaseUrl = "http://svcs.ebay.com/services/search/FindingService/v1?OPERATION-NAME="; //base url api end point 

      if (calltype == "categoryClick") 
      { 
       string Url = BaseUrl + OperationName + "&SERVICE-VERSION=1.0.0&SECURITY-APPNAME=" + AppId + "&RESPONSE-DATA-FORMAT=XML&REST-PAYLOAD&categoryId=" + categoryId + "&paginationInput.entriesPerPage=2&paginationInput.pageNumber=" + page + ""; 
       var client = new RestClient(Url); 
       var request = new RestRequest(Method.GET); 
       request.Method = Method.GET; 
       request.Parameters.Clear(); 
       var xmlResponse = client.Execute(request).Content; 

       XmlDocument xdoc = new XmlDocument(); 
       xdoc.LoadXml(new WebClient().DownloadString(xmlResponse)); 


       var items = new List<EbayDataViewModel>(); 

       foreach (var item in items) 
       { 
        //add items from xml data to EbayDataViewModel object 

       } 

      } 
      return View(); 
     }

视图模型：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using WebApplication2.Models; 

namespace WebApplication2.ViewModels 
{ 
    public class EbayDataViewModel 
    { 
     public string EbayImageUrl { get; set; } 
     public string EbayTitle { get; set; } 
     public string NumberOfSales { get; set; } 
     public string NumberOfWatch { get; set; } 
    } 


}

您可以通过[XmlDocument.SelectNodes方法]（https://msdn.microsoft.com/en-us/library/system.xml.xmldocument.selectnodes（v = vs.110）的.aspx）。您不应该指定非常复杂的xpath - 有关示例，请参阅[这里]（https://www.w3schools.com/xml/xpath_examples.asp）。 – Poosh

如果你不使用.NET 3.0或更低，强烈建议使用XDocument而不是XmlDocument：reference link

无论如何，你可以使用.Descendants()让所有后代，然后比较其所有元素的本地名，看是否有一个元素，它的本地名称项目的名称相匹配。

（测试）

var items = new List<EbayDataViewModel>(); 

// You can directly plug the url in with .Load() method. 
// No need to create HttpClient to download the response as string and then 
// parse. 
XDocument xdoc = XDocument.Load(url); 

// Since you're only interested in <item> collections within <searchResult> 
var searchResultItems = xdoc.Descendants() 
    .Where(x => x.Name.LocalName == "item"); 

foreach (var sri in searchResultItems) 
{ 
    // Get all child xml elements 
    var childElements = sri.Elements(); 

    var itemId = childElements.FirstOrDefault(x => x.Name.LocalName == "itemId"); 
    var title = childElements.FirstOrDefault(x => x.Name.LocalName == "title"); 

    //add items from xml data to EbayDataViewModel object 
    items.Add(new EbayDataViewModel { 
     EbayTitle = title == null? Stirng.Empty : title.Value, 
     ... 
    }); 
} 

return items;

由于有大量的检查和比较，写extention方法对于那些将是有益的。

public static class XElementExtensions 
{ 
    public static XElement LocalNameElement(this XElement parent, string localName) 
    { 
     return parent.Elements().FirstOrDefault(x => x.Name.LocalName == localName); 

    public static IEnumerable<XElement> LocalNameElements(this XElement parent, string localName) 
    { 
     return parent.Elements().Where(x => x.Name.LocalName == localName); 
    } 

    public static string LocalNameElementValue(this XElement parent, string localName) 
    { 
     var element = parent.LocalNameElement(localName); 
     return element == null? String.Empty : element.Value; 
    } 

    ... 
}

https://ibb.co/hpDPiw检查此屏幕截图。我收到错误：'路径中的非法字符'。 –

你可以给我的网址，以便我可以插入到我的休息客户端？ –

//工作网址：http://svcs.ebay.com/services/search/FindingService/v1?OPERATION-NAME=findItemsByCategory&SERVICE-VERSION=1.0.0&SECURITY-APPNAME=KavinHim-BestProd-PRD-78e3e6bf1-97d9ef25&RESPONSE-DATA- FORMAT = XML＆REST-PAYLOAD＆categoryId = 37903＆paginationInput.entriesPerPage = 100＆paginationInput.pageNumber = 4 –

一种方法是从你的XmlDocument使用XPath查询字符串来访问项目节点值。你可能要循环的响应项目，并创建新的视图模型对象来填充你的ViewModels的列表：

var items = new List<EbayDataViewModel>(); 
var responseItems = xdoc.SelectNodes("item"); 
foreach (responseItem in responseItems) 
{ 
    items.Add(new EbayDataViewModel() 
     { EbayImageUrl = responseItem.SelectSingleNode("galleryURL").InnerText, 
      EbayTitle = responseItem.SelectSingleNode("title").InnerText, 
      NumberOfSales = responseItem.SelectSingleNode("").InnerText, 
      NumberOfWatch = responseItem.SelectSingleNode("").InnerText 
     }); 
}

注：我无法找到任何东西，看起来像在XML响应“NumberOfSales或NumberOfWatch” ，因此需要填写那些XPath。

有关此方法的文档，请参阅XmlDocument.SelectNodes。
