Notepad++ Regex: Match all occurrences after another match

How to match all occurrences after another match?

For example: I want to replace all - after abc with space.

Input:

one-two-abc-three-four-five
six-seven-abc-eight-nine-ten
...

Output:

one-two-abc three four five
six-seven-abc eight nine ten
...

In Javascript is possible to use this regex: (?<=(.+abc.+))-, but the Positive Lookbehind seems not to be supported in Notepad++

Thanks.

PS: Feel free to correct the Title. I did my best, but I'm not native speaker.

This will work with any number of hyphens in the string.

• Ctrl+H
• Find what: (?:^.*abc|\G[^-\r\n]+)\K-
• Replace with: # a single space
• CHECK Match case
• CHECK Wrap around
• CHECK Regular expression
• UNCHECK . matches newline
• Replace all

Explanation:

(?: # non capture group ^ # beginning of line .* # 0 or more any character but newline abc # literally abc | # OR \G # restart from last match position [^-\r\n]+ # 1 or more any character that is not hyphen or line break
) # end group
\K # forget all we have seen until this position
- # hyphen

I found this solution.

Find:
^(.+abc)(-([^-]*))?(-([^-]*))?(-([^-]*))?(-([^-]*))?(-([^-]*))?(-([^-]*))?$
Replace:
$1 $3 $5 $7 $11 $13

These caveats you need to be aware of:

1. All wanted (replaced) occurrences of - are after the last occurrence of abc.
2. (-([^-]*))? part of regex is repeated equally or more than max. count of - in a single line.
3. There will be extra spaces on end of each line which has less - occurrences than (-([^-]*))? count in the regex
4. Number after $ in replace expression is start by 1 and is +2 for each (-([^-]*))? occurrence.
