我有3起事故，其中2條評論有相同的時間<Comment>Entry Date: Tuesday, 31 12 2013 on 00:13:23我需要刪除其中的一個我是新來的XML和嘗試這個，但不是成功。

private void button2_Click(object sender, EventArgs e) 
     { 
    XmlDocument xdoc1 = new XmlDocument(); 
       xdoc1.Load("C:\\Users\\IT-Administrator\\Desktop\\2014-01-07_Middlesex.xml"); 
       XmlNodeList Incidents = xdoc1.SelectNodes("//Incidents"); 
       List<string> IncidentsSeen = new List<string>(); 


       foreach (XmlNode comments in Incidents) 
       { 
        string EntryDate = Incidents.Attributes["Comments"].value; 
         if(IncidentsSeen.Contains(EntryDate)) 
          Incidents.ParentNode.RemoveChild(Incidents); 
         else 
          IncidentsSeen.Add(EntryDate); 
       } 
       Console.ReadKey(true); 
      } 
       } 
       xdoc1.Save("X:\\Processed\\2013-07-06_Iceland_-_Spennymoorduplicate.xml");

您的xml無效（證據）。 – dovid

你將不得不以某種方式解析這個日期。這是最大的障礙。你能確定日期格式嗎？ – Gusdor

是的，這是我的問題..日期格式是2013-12-31 T 11:21:27 – preethi

請試試這個我已經包括示例XML但是我沒有將命名空間。

XDocument xdoc1 = XDocument.Load(@"D:\xxxx\Xxxxxxx\xxxx\TrialXML.xml"); 

xdoc1.Root.Elements("Incident") 
.OrderBy(d=>(Convert.ToDateTime(Convert.ToString(d.Element("EntryTime").Value)))) 
.GroupBy(s => (string)s.Element("Comment")) 
.SelectMany(g => g.Skip(1)) 
.Remove(); 

xdoc1.Save(@"D:\xxxx\Xxxxxxx\xxxx\TrialXML.xml");

按你的意見

加載多個XML文件，並可以將它們合併成一個。

var xml1 = XDocument.Load("file1.xml"); 
    var xml2 = XDocument.Load("file2.xml"); 

xml1.Descendants("Incident").LastOrDefault().AddAfterSelf(xml2.Descendants("Incident"‌)); 
xml1.Save();

希望它能幫助 - Reference

UPDATE根據您的意見，試試這個從RichTextBox加載XML。

string test = richTextBox1.Text; 
TextReader tr = new StringReader(test); 
XDocument doc = XDocument.Load(tr);

解決了..謝謝guys..is有任何方式來從加載按鈕上載多個XML文件。 – preethi

@preethi上傳多個xml文件？你的意思是選擇多個XMl文件嗎？我可以問你爲什麼只是爲了理解。 –

我有多個xml文件，清楚地說，我有多個停車場位置，每個停車場位置都與不同的車輛和theri時間相同的強大功能。 – preethi

使用LINQ to XML：

var doc = XDocument.Load(@"C:\Users\IT-Administrator\Desktop\2014-01-07_Middlesex.xml"); 
List<string> IncidentsSeen = new List<string>(); 

foreach (var item in doc.Element("Incidents").Elements("Incident")) 
{ 
    var EntryDate = item.Element("Comment").Value; 
    if (IncidentsSeen.Contains(EntryDate)) 
    { 
     item.Remove(); 
    } 
    else 
    { 
     IncidentsSeen.Add(EntryDate); 
    } 
} 

doc.Save(@"C:\Users\IT-Administrator\Desktop\2014-01-07_Middlesex.xml");

注意： EntryDate是不是日期時間

編輯

在文件只是不同的元素：

var doc = XDocument.Load(@"C:\Users\IT-Administrator\Desktop\2014-01-07_Middlesex.xml"); 

foreach (var itemsGroup in doc.Element("Incidents").Elements("Incident").GroupBy(x => x.Element("Comment").Value)) 
{
