我想将以下xml文件拆分为4个单独的部分（我需要放置链接，因为它的发布时间太长了：

我不需要的部分，我只需要xml文件的这4部分。我该如何轻松拆分？有些元素被多次命名。

Answer 1

我将使用XMLDocument读取器/写入器。您可以在内存中操纵所需的元素。

可以在以下主题中找到大量文档：using xmldocument to read xml

Answer 2

您仅在链接上发布了第1部分。下面我使用xml linq来获取元素。如果文件很大，则还需要使用xmlreader

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";

        static void Main(string[] args)
        {
            XDocument doc = XDocument.Load(FILENAME);
            XElement resprocessing = doc.Descendants("resprocessing").FirstOrDefault();

            string header = "<?xml version=\"1.0\" encoding=\"utf-8\"?><resprocessing></resprocessing>";
            XDocument newDoc = XDocument.Parse(header);
            XElement newResprocessing = newDoc.Root;
            newResprocessing.ReplaceWith(resprocessing);
        }
    }
}
