使用c＃替换html中的标签范围之间的文本 [英] Replace text between tags span in html with c#

问题描述

大家好。我正在使用Windows窗体中的项目，我需要在html文档中的标签之间替换文本。我写了以下代码：

Hello guys. I am working on my Project in Windows Forms and I need to replace text between tags span in html Document. I have following Code written:

string pattern = "<span class=\"nameLastname\">(.*)</span>";
string nameLastnamePattern = "<span class=\"nameLastname\">"+name+ lastname+"</span>";

System.IO.StreamReader objReader;
objReader = new StreamReader(System.IO.Directory.GetCurrentDirectory() + "\\intel\\main.html");
string content = objReader.ReadToEnd();
objReader.Close();

content = Regex.Replace(content,pattern, nameLastnamePattern);

StreamWriter writer = new StreamWriter(System.IO.Directory.GetCurrentDirectory() + "\\intel\\main.html");
writer.Write(content);
writer.Close();

我想替换例如< span class =nameLastname> George< / span> width< span class =nameLastname> Dave< / span> 。但我的代码不起作用。任何人都可以帮我吗？

I want to Replace for example "<span class="nameLastname">George</span>" width "<span class="nameLastname">Dave</span>" . But my code donn't work. Can anyone Help me with it ?

推荐答案

试试这个：

Try this:

public static Regex regex = new Regex(
      "(?<=<span class=\ \ \"nameLastname\ \ \">)(?<Name>.*)(?=</span>)",
    RegexOptions.Singleline
    | RegexOptions.CultureInvariant
    | RegexOptions.Compiled
    );
// This is the replacement string
public static string regexReplace = 
      "Dave";
// Replace the matched text in the InputText using the replacement pattern
string result = regex.Replace(InputText,regexReplace);

[edit]Remove the spaces between the backslashes - otherwise Markdown swallows parts of the regex...[/edit]
