A small example of using the Notepad ++ regular expression to complete complicated replacement

Problem description

================

Find hundreds of lines of code on the network and copy it to a local device for testing.

To make the blog look good, the Code author adds a line number to the code.

After the code is copied, the front of each line contains a numeric row number and a vertex.

 

 

If you want to manually delete these line numbers and points, the code of a dozen lines will be taken care of, but the hundreds of lines of code won't hurt in time.

So I studied the replacement of Notepad ++ Regular Expressions by the way.

 

Try

==================

At the beginning, I wrote the following replacement formula:

Search:

\ D {1, 3 }\.

Replace:

Blank

The result is not work.

 

After further research, we found that the regular expressions supported by notepad ++ are a little different from those supported by normal regular expressions.

I found the help document of Notepad ++ and wrote another expression in the supported format.

Search:

\ D + \.

Replace:

Blank

 

Successful!

Solve the problem.
