我有 3 个事件，其中 2 个 cmets 有相同的时间 &lt;Comment&gt;Entry Date: Tuesday, 31 12 2013 on 00:13:23 我需要删除其中一个我是 xml 新手并尝试过但没有成功。

 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");
            }

【问题讨论】：

  • 您的 xml 无效（证据）。
  • 您将不得不以某种方式解析该日期。这是最大的障碍。你能确定日期格式吗？
  • 是的，那是我的问题.. 日期格式是 2013-12-31 T 11:21:27

标签： c# xml


【解决方案1】：

请试试这个，我已经包含了一个示例 XML，但是我没有包含命名空间。

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cmets

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();

希望对您有所帮助 -Reference

更新根据您的 cmets，尝试从 RichTextBox 加载 XML。

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

【讨论】：

  • 解决了..谢谢大家..有没有办法从加载按钮上传多个xml文件。
  • @preethi 上传多个 xml 文件？你的意思是选择多个 XMl 文件对吗？我能问你为什么你需要它来理解。
  • 我有多个 xml 文件，很明显我有多个停车场位置，每个停车场位置都有相同的内容，不同的车辆和不同的时间。
  • @preethi 您是否需要将多个文件保存到一个 XML 中，如果是，请检查更新的答案。或者您可以创建一个函数将多个 xml 文件合并为一个。
  • 嘿 Suraj 感谢您帮助我。您能告诉我如何使用 c# 中富文本框中的 xml 文件吗？请加急.......
【解决方案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 不是 DateTime

编辑

仅针对文件中的不同元素：

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))
{
    foreach (var item in itemsGroup.Skip(1))
    {
        item.Remove();
    }
}

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

【讨论】：

  • 感谢 lomed 尝试过，但没有显示任何错误，但文件保持不变。
  • 我可以肯定地说它的工作，但我有 3 行相同的数据它删除了第二个节点但第三个节点仍然存在..我不知道你在做什么..
  • 发布一个有效的 xml。和所需的输出 xml。
  • 你能告诉我如何附加一个xml文件，这样你就可以了解它了。
  • @preethi 只需复制粘贴您的 Xml 并在选择 xml 后使用 {} 将其显示为代码块。
