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.
