除Delphi上的整个单词外，是否有任何函数/过程作为ReplaceString？ [英] Is there any function/procedure as ReplaceString but for whole words on Delphi?

问题描述

是否有任何函数/过程，如 ReplaceString ，但对于Delphi上的整个单词呢？我只需要在整个单词替换掉新的子字符串。例如：

Is there any function/procedure as ReplaceString but for whole words on Delphi? I just need to replace substring to the new one when it's a whole word. For example:

substring - > newstring
substring, -> newstring
substring123 -> substring

推荐答案

您可以使用内置的正则表达式库来做这个。例如：

You can use the built-in regex library to do this. For example:

{$APPTYPE CONSOLE}

uses
  System.RegularExpressions;

const
  InputString = 'a Substring, substring123, some more text';

begin
  Writeln(TRegEx.Replace(InputString, '\bsubstring\b', 'newstring', [roIgnoreCase]));
end.
