Using regex to substitute newline characters

I'm interested in enhancing a regex in JavaScript that detects new lines or line breaks and converts them to carriage returns. - Yep, Photoshop's text feature is a bit outdated.

  • "hello\nworld"
  • "hello
    world"

All of the above examples should be replaced with

-hello/rworld

I understand that the second example above is treated as an actual line break

So far, I've had to use two separate regex patterns, but I'm really looking for a single one that can handle both scenarios (multiple times). However, I haven't been successful in combining them effectively.

// replace \n with \r carriage return
var rexp = new RegExp(/\\n/gi)
content = content.replace(rexp , "\r")

// replace <br> with \r carriage return
rexp = new RegExp(/<br>/gi)
content = content.replace(rexp , "\r")

Thanks.

Answer №1

To efficiently replace line breaks and HTML line breaks, you can utilize the "special | or" operator in JavaScript:

content = content.replace(/\n|<br\s*\/?>/gi, "\r");

This method will effectively handle the following scenarios:

"hello\nworld"
"hello<br>world"
"hello<br />world"
