Solve the problem of having a row number (Regular Expression to remove the code row number)

For exampleCodeAs follows:

6.
7. < Meta Name = "Generator" Content = "Editplus" >
......
263. </ Body >
264.
265. </ Html >

 

 

Is it annoying to have a row number?

I often have two solutions. You must know that regular expressions are used.

Method 1:

To use the search and replacement functions of common development tools, you must support regular expressions, such as my commonly used text editor notepad ++.

Open Search replacement (CTRL + H), select regular mode, regular expression: ^ \ s * \ D + \.

 

Method 2: If your development tool is not easy to use, you can download and use this regular expression testing tool.
