当我尝试删除依赖于IDtextbox.text的Mobile元素而不是XPath表达式中的静态值时，它不会执行

我在Visual Studio 2010中使用Windows应用程序，C＃语言

我需要两个例子： 1-取决于父元素内的元素。 2-取决于父元素的属性，确保该属性不是整数值，它是代码。 注意：我搜索了很多网站并查看了多个解决方案，没有提到在XPath表达式中使用控制值。

使用xml linq，在这种情况下比xpath

更好 
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);

            List<XElement> mobiles = doc.Descendants("Mobile").ToList();

            mobiles = mobiles.Where(x => (string)x.Element("FullName") != "Galaxy S-4").ToList();

            mobiles = mobiles.Where(x => (string)x.Attribute("RegDate") != "26/05/2017").ToList();

            doc.Descendants("Mobiles").FirstOrDefault().ReplaceWith(new XElement("Mobiles", mobiles));
        }
    }
}

答案 1 :(得分：0)

谢谢，朱德文先生 我用这段代码解决了这个问题

XDocument doc = XDocument.Load(@"Mobiles.xml");
List<XElement> mobiles = doc.Descendants("Mobile").ToList();
//mobiles = mobiles.Where(x => (string)x.Element("ID") == ID).ToList();
mobiles = mobiles.Where(x => (string)x.Attribute("ID") == ID).ToList();
doc.Descendants("Mobile").FirstOrDefault().ReplaceWith();

祝你好运
