从 SHAREPOINT REST API 结果中读取 XML 值

Question

请问如何在 foreach 循环或 for 循环中从 SHAREPOINT RESTAPI 结果中读取 XML 值？

这是我的源代码，我想读取 d:Title,d:Description,and d:Follow/d:Url

的值

XmlNamespaceManager xmlnspm = new XmlNamespaceManager(new NameTable());
Uri sharepointUrl = new Uri("SHAREPOINT URL);

xmlnspm.AddNamespace("atom", "http://www.w3.org/2005/Atom");
xmlnspm.AddNamespace("d", "http://schemas.microsoft.com/ado/2007/08/dataservices");
xmlnspm.AddNamespace("m", "http://schemas.microsoft.com/ado/2007/08/dataservices/metadata");

NetworkCredential cred = new System.Net.NetworkCredential("USERNAME", "PASSWORD", "DOMAIN");

HttpWebRequest listRequest = (HttpWebRequest)HttpWebRequest.Create(sharepointUrl.ToString() + "_api/lists/getByTitle('" + "LIST NAME" + "')/items");
listRequest.Method = "GET";
listRequest.Accept = "application/atom+xml";
listRequest.ContentType = "application/atom+xml;type=entry";

listRequest.Credentials = cred;
HttpWebResponse listResponse = (HttpWebResponse)listRequest.GetResponse();
StreamReader listReader = new StreamReader(listResponse.GetResponseStream());
XmlDocument listXml = new XmlDocument();

listXml.LoadXml(listReader.ReadToEnd());

和我的示例 XML 文件：

尝试了几种方法后，我找到了解决方案。

这里有我的示例源代码。

    // Get and display all the title and Description
                XmlElement root = listXml.DocumentElement;
                XmlNodeList elemList = root.GetElementsByTagName("content");
                XmlNodeList elemList_title = root.GetElementsByTagName("d:Title");
                XmlNodeList elemList_desc = root.GetElementsByTagName("d:Description");



                for (int i = 0; i < elemList.Count; i++)
                {

                    string title = elemList_title[i].InnerText;
                    string description = elemList_desc[i].InnerText;
            Console.WriteLine(title+description);

                }

我建议您使用 JSON 访问 REST，我们可以更轻松地获得结果。

示例代码:

using Newtonsoft.Json;  
using Newtonsoft.Json.Linq;  


namespace REST  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            HttpWebRequest endpointRequest = (HttpWebRequest)HttpWebRequest.Create("Site URL/_api/web/lists/getByTitle(List Name')/items");  

            endpointRequest.Method = "GET";  
            endpointRequest.Accept = "application/json;odata=verbose";  
            NetworkCredential cred = new System.Net.NetworkCredential("username", "password", "domain");  
            endpointRequest.Credentials = cred;  
            HttpWebResponse endpointResponse = (HttpWebResponse)endpointRequest.GetResponse();  
            try  
            {  
                WebResponse webResponse = endpointRequest.GetResponse();  
                Stream webStream = webResponse.GetResponseStream();  
                StreamReader responseReader = new StreamReader(webStream);  
                string response = responseReader.ReadToEnd();  
                JObject jobj = JObject.Parse(response);  
                JArray jarr = (JArray)jobj["d"]["results"];  
                foreach (JObject j in jarr)  
                {  
                    Console.WriteLine(j["Title"]+" "+j["Body"]);  
                }  

                responseReader.Close();  
                Console.ReadLine();  


            }  
            catch (Exception e)  
            {  
                Console.Out.WriteLine(e.Message); Console.ReadLine();  
            }       
        }  
    }  
}
