Regular expressions replace strings with another string in MS Word?

filename_author

author_filename

This is a regular expression:

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

This is a C# example:

< /p>

using System;
using System.Text.RegularExpressions;

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

This is a Python example:

from re import sub

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

Edit: In order to use wildcards in Microsoft Word To do this, use it as a search string:

(<*>)_(<*>)

and replace with:

_


< p>Also, see Add power to Word searches with regular expressions for an explanation of the syntax I used above:

• 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.

Anyone can help me change the regular expression:

filename_author

to

author_filename

I am using MS Word 2003, and I am trying to use Word’s Find and Replace. I have tried using the wildcard function, but no luck.

Can I only do it programmatically?

This is a regular expression:

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

This is a C# example:

using System;
using System.Text.RegularExpressions;

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

This is a Python example:

from re import sub

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