從動態asp腳本讀取動態xml

Question

我正嘗試讀取由ASP腳本創建的動態xml，但不幸的是我無法讀取。看來我的C＃代碼無法理解ASP腳本。

我很樂意聽到一些建議。

你可以看到ASP腳本的位置：http://www.ad-net.co.il/test.asp

<% 
Response.Buffer = True 
Response.ContentType = "text/xml" 
body = "" 
body = body & "<?xml version=""1.0"" encoding=""utf-8""?>" 
body = body & "<PROGRAM>" 
body = body & "<EMAIL>email@gmail.com</EMAIL>" 
body = body & "<USERNAME>username@gmail.com</USERNAME>" 
body = body & "<PASSWORD>password</PASSWORD>" 
body = body & "</PROGRAM>" 
Response.Write(body) 
%> 

的C＃代碼：

private static void LoadXmlFromServerToProgram() 
    { 
     try 
     { 
      XmlDocument xDoc = new XmlDocument(); 
      xDoc.Load("http://www.ad-net.co.il/test.asp"); 

      EMAIL = xDoc.DocumentElement.SelectSingleNode("EMAIL").InnerText; 
      USERNAME = xDoc.DocumentElement.SelectSingleNode("USERNAME").InnerText; 
      PASSWORD = xDoc.DocumentElement.SelectSingleNode("PASSWORD").InnerText;     
     } 
     catch 
     { 
      MessageBox.Show("Can't Read From XML"); 
     } 
    } 

Answer 1

您不應該使用的SelectSingleNode這樣..你需要一個XPath查詢，而不是單個頂級節點。 Look here for information on XPath。

你需要嘗試是這樣的：

EMAIL = xDoc.CreateNavigator().SelectSingleNode("/PROGRAM/EMAIL").Value;

試試這個：你有（異常信息，或者是意外的行爲，你觀察問題
