我有3个事件，其中2个评论同时<Comment>Entry Date: Tuesday, 31 12 2013 on 00:13:23我需要删除其中一个我是xml的新手，并尝试了这个但不是为了成功。

 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");
            }

这是我的完全MXL代码::::

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");

根据你的意见

加载多个Xml文件，您可以将它们合并为一个。

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

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

希望有所帮助 - Reference

更新根据您的评论，请尝试从RichTextBox加载XML。

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

Answer 2

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 不 DateTime

修改

仅用于文件中的不同元素：
