如何找到網頁上的

Question

對於下列網頁XML： http://www.realclearpolitics.com/epolls/2012/president/us/general_election_romney_vs_obama-1171.html

我將如何去尋找與圖表中的數據相關的XML。我知道XML頁面是http://charts.realclearpolitics.com/charts/1171.xml，因爲有人告訴我。但是，我怎麼會認爲我自己呢？

感謝

Answer 1

通常你可以在網站上找到的RSS鏈接或查看頁面的源代碼和搜索.XML

您還可以使用在谷歌以下查詢：

網站： realclearpolitics.com filetype：xml

Answer 2

您是否試過以下linq xml？

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Xml; 
using System.Xml.Linq; 


namespace ConsoleApplication1 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      XDocument doc = XDocument.Load("http://charts.realclearpolitics.com/charts/1171.xml"); 

     } 
    } 
}

我終於得到它來繪製

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 
using System.Windows.Forms.DataVisualization.Charting; 
using System.Xml; 
using System.Xml.Linq; 
using System.IO; 

namespace WindowsFormsApplication1 
{ 
    public partial class Form1 : Form 
    { 
     public Form1() 
     { 
      InitializeComponent(); 
      XDocument doc = XDocument.Load("http://charts.realclearpolitics.com/charts/1171.xml"); 
      var results = new { 
       X = doc.Descendants("series").Descendants("value").Select(y => (DateTime)y).ToList(), 
       Obama = doc.Descendants("graph").Where(y => y.Attribute("title").Value == "Obama").Descendants("value").Select(y => (string)y == "" ?null : (double?)y).ToList(), 
       Romney = doc.Descendants("graph").Where(y => y.Attribute("title").Value == "Romney").Descendants("value").Select(y => (string)y == "" ?null : (double?)y).ToList() 
      }; 


      chart1.Series.Add("Obama"); 
      chart1.Series["Obama"].ChartType = SeriesChartType.Point; 
      chart1.Series["Obama"].Points.DataBindXY(results.X, results.Obama); 
      chart1.Series.Add("Romney"); 
      chart1.Series["Romney"].ChartType = SeriesChartType.Point; 
      chart1.Series["Romney"].Points.DataBindXY(results.X, results.Romney); 
      chart1.DataBind(); 

     } 
    } 
}
