这是XML文件的一部分，有太多这样的＆lt;容器＆gt; 在我的XML文件中。此处信号的名称在标签＆lt;中定义SHORT-NAME＆gt; ，我想更改＆lt;标签的 innertext 标签＆lt;中存在VALUE＆gt; 功能名称值> ，信号名称带有一些前缀。例如：RTE_ComCbk_ SignalName 。

这必须在XML文件中存在的所有不同容器中完成。

请注意：所有容器的结构保持不变，只有标签中的内部文本因容器而异。我能写出上面说的＆lt;的前缀值＆gt; 标记，我应该如何为标记＆lt;分配信号名称？值＆gt; ??

我该怎么办？

 private void button11_Click(object sender, EventArgs e)
    {
    int count_ComTimeoutNotification = 0;
    XmlNodeList comTimeoutNotificationList = doc.GetElementsByTagName("DEFINITION-REF");
    int NodeListCount = comTimeoutNotificationList.Count;
    for (int i = 0; i < NodeListCount; i++)
        {


            if ((string)comTimeoutNotificationList[i].InnerText == "/AUTOSAR/Com/ComConfig/ComSignal/ComTimeoutNotification")
            {

                if ((string)comTimeoutNotificationList[i].NextSibling.Name == "VALUE")
                {
                    comTimeoutNotificationList[i].NextSibling.InnerText = "_Shree";
                    count_ComTimeoutNotification++; //this line is for reference if its changing the exact no.of time that is reqd.
                }
            }
        }

doc.Save（OpenFileDialog1.FileName）; }

Answer 1

使用XML Linq

尝试这样的事情

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


namespace ConsoleApplication85
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XDocument doc = XDocument.Load(FILENAME);
            XNamespace ns = ((XElement)doc.FirstNode).Name.Namespace;

            List<XElement> containers = doc.Descendants(ns + "CONTAINER").ToList();
            foreach (XElement container in containers)
            {
                var definition_Ref = container.Descendants(ns + "FUNCTION-NAME-VALUE")
                    .Where(x => x.Descendants(ns + "DEFINITION-REF").Count() > 0).ToList();
                if (definition_Ref.Count > 0)
                {
                    string shortName = (string)container.Element(ns + "SHORT-NAME");
                    if (shortName.Length > 0)
                    {
                        List<XElement> functionName = definition_Ref
                            .Where(x => x.Value.Contains("/AUTOSAR/Com/ComConfig/ComSignal/ComTimeoutNotification"))
                            .ToList();
                        XElement value = functionName.Elements("VALUE").FirstOrDefault();
                        if (value != null)
                        {
                            value.Value = shortName + "_" + value.Value;
                        }
                    }
                }
            }
        }
    }
}

没有必要使用XML Linq你已经拥有的check this jsfiddle link应该能够使用XmlDocument和SelectNodes方法以及像这样的SelectSingleNodes这样做：

Answer 3

 private void button11_Click(object sender, EventArgs e)
    {
        XmlNodeList comTimeoutNotificationList = doc.GetElementsByTagName("DEFINITION-REF");
        int NodeListCount = comTimeoutNotificationList.Count;
        foreach (XmlNode node in comTimeoutNotificationList)
        {
            if (node.InnerText == "/AUTOSAR/Com/ComConfig/ComSignal")
            {
                if(node.PreviousSibling.Name == "SHORT-NAME")
                shortName = node.PreviousSibling.InnerText;
            }
            if (node.InnerText == "/AUTOSAR/Com/ComConfig/ComSignal/ComTimeoutNotification")
            {
                node.NextSibling.InnerText ="ComTout_" +  shortName;
                listBox1.Items.Add(node.NextSibling.InnerText);
            }
            else if(node.InnerText == "/AUTOSAR/Com/ComConfig/ComSignal/ComNotification")
            {
                node.NextSibling.InnerText = "ComNoti_" + shortName;
                listBox1.Items.Add(node.NextSibling.InnerText);
            }
            else if(node.InnerText == "/AUTOSAR/Com/ComConfig/ComSignal/ComInvalidNotification")
            {
                node.NextSibling.InnerText = "ComInval" + shortName;
                listBox1.Items.Add(node.NextSibling.InnerText);
            }
        }

    }
