使用XDocument对文件进行一些修改后，如何在xml文件中保留十六进制字符？ 例如，这是我在任何操作之前的文件

这是在使用修改后的 Cylian 建议的方法

程序代码

void Button1Click(object sender, EventArgs e)
{
var basePath = textBox1.Text;
string[] filesindirectory = Directory.GetFiles(basePath, "*.xml",SearchOption.AllDirectories);
foreach (string fp in filesindirectory)
{
string file_content = escape_string(File.ReadAllText(fp), 0);
XDocument doc = XDocument.Parse(file_content, LoadOptions.PreserveWhitespace);
doc.Descendants("name").Elements().Remove();
File.WriteAllText(fp, escape_string(doc.ToString(), 1).ToString());
}
MessageBox.Show("Done");
}
private static string escape_string (string input_string, int option){
switch (option)
{
case 0:
return input_string.Replace("&", "&amp;").ToString();
case 1:
return input_string.Replace("&amp;", "&").ToString();

return null;

}
}

行<?xml version="1.0" encoding="UTF-8"?>已删除，<!DOCTYPE article PUBLIC "-//NLM//DTD JATS (Z39.96) Journal Publishing DTD with OASIS Tables v1.0 20120330//EN" "JATS-journalpublishing-oasis-article1.dtd">也更改为<!DOCTYPE article PUBLIC "-//NLM//DTD JATS (Z39.96) Journal Publishing DTD with OASIS Tables v1.0 20120330//EN" "JATS-journalpublishing-oasis-article1.dtd"[]>。 为什么会这样？

用于更清晰的简化代码，简单的控制台应用程序来演示技巧：

Program.cs 

using System;
using System.IO;
using System.Xml.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                var basePath = Console.ReadLine();
                string[] filesindirectory = Directory.GetFiles(basePath, "*.xml");
                foreach (string fp in filesindirectory)
                {
                    string file_content = escape_string(File.ReadAllText(fp), 0);
                    XDocument doc = XDocument.Parse(file_content, LoadOptions.PreserveWhitespace);
                    XElement test = new XElement("path", fp.ToString());
                    doc.Root.Add(test);
                    File.WriteAllText(Path.ChangeExtension(fp, "out"), escape_string(doc.ToString(), 1).ToString());
                }
            }
            catch (Exception ex)
            {
                Console.Write(ex.ToString());
            }
            Console.ReadKey();
            return;
        }
        private static string escape_string (string input_string, int option){
            switch (option)
            {
                case 0:
                    return input_string.Replace("&", "&amp;").ToString();
                case 1:
                    return input_string.Replace("&amp;", "&").ToString();
                default:
                    return null;

            }
        }
    }
}

希望这可以提供帮助。 （同样，这只是一个快速而肮脏的技巧，已有更好的选择）...... :)
