正则表达式用MS Word中的另一个字符串替换字符串？

任何人都可以帮助我改变正则表达式：

filename_author

至

author_filename

我正在使用MS Word 2003,并尝试使用Word的查找和替换.我尝试过使用通配符功能,但没有运气.

我只能以编程方式进行吗？

解决方法

这是正则表达式：

([^_]*)_(.*)

这是一个C#示例：

using System;
using System.Text.RegularExpressions;

class Program
{
    static void Main()
    {
        String test = "filename_author";
        String result = Regex.Replace(test,@"([^_]*)_(.*)","$2_$1");
    }
}

这是一个Python示例：

from re import sub

test = "filename_author";
result = sub('([^_]*)_(.*)',r'\2_\1',test)

编辑：为了在Microsoft Word中使用通配符执行此操作,请将其用作搜索字符串：

(<*>)_(<*>)

并替换为：

\2_\1

另外,请参阅Add power to Word searches with regular expressions以获取我上面使用的语法的解释：

• The asterisk (*) returns all the text in the word.
• The less than and greater than symbols (< >) mark the start and end
  of each word,respectively. They
  ensure that the search returns a
  single word.
• The parentheses and the space between them divide the words into distinct groups: (first word) (second word). The parentheses also indicate the order in which you want search to evaluate each expression.
