將Xml文件拆分為多個部分

Question

我想將以下xml文件分為4個單獨的部分（我需要放置鏈接，因為鏈接很長，無法在此處發布：

https://www.dropbox.com/s/dzqyab0wewpuf5t/1547917556__0__qti_166292.xml?dl=0

我想了解以下部分：第1部分：

我不需要的部分，我只需要xml文件的這4部分。 我該如何輕松拆分？ 有些元素被多次命名。

Answer 1

我將使用XMLDocument讀取器/寫入器。 您可以在內存中操縱所需的元素。

可以在該主題上找到大量文檔，例如： 使用xmldocument讀取xml

Answer 2

您僅在鏈接上發布了第1部分。 下面我使用xml linq來獲取元素。 如果文件很大，則還需要使用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);
        }
    }
}
