c# - 如何用 XDT 转换替换字符串

Question

我要转换的配置如下所示:

<sdfsdfsd>

<blah>
<mypath>D:\my\old\path\aaa</mypath>
</blah>

<blah>
<mypath>D:\my\old\path\bbb</mypath>
</blah>

<blah>
<mypath>D:\my\old\path\ccc</mypath>
</blah>

</sdfsdfsd>

我只想替换 D:\my\old\path\<unique value>与 D:\my\new\path\<unique value>

我只看到示例替换 <><> 之间的完整值或 <> 内的属性。我只想在文件中的任何地方做一个简单的字符串替换，这可能吗？

试试 xml linq

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string xml = 
                "<sdfsdfsd>" +
                    "<blah>" +
                    "<mypath>D:\\my\\old\\path\\aaa</mypath>" +
                    "</blah>" +
                    "<blah>" +
                    "<mypath>D:\\my\\old\\path\\bbb</mypath>" +
                    "</blah>" +
                    "<blah>" +
                    "<mypath>D:\\my\\old\\path\\ccc</mypath>" +
                    "</blah>" +
                "</sdfsdfsd>";

            XElement element = XElement.Parse(xml);

            foreach(XElement mypath in  element.Descendants("mypath"))
            {
                mypath.SetValue(((string)mypath).Replace("old","new"));
            }

        }
    }
}
