正则表达式用 MS Word 中的另一个字符串替换字符串？

Question

任何人都可以用正则表达式帮我转:

filename_author

到

author_filename

我正在使用 MS Word 2003 并尝试使用 Word 的“查找和替换”来执行此操作。我试过 use wildcards功能，但没有任何运气。

我只能以编程方式完成吗？

Answer 1

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

另请参阅 Add power to Word searches with regular expressions有关我在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.
