How to remove all the lines between two patterns in notepad++?

Question

I'm trying to replace the below text

"{print next
error
incorrect
err
}end"

to

"{print }end"

any I'm using (\{print)(.*?)(\}end) but not working. Deleting everything from print and end will also work

Answer 1

I'm getting familiar day by day to Regex usage, so here I share my approach ....

Find what: next[\s\S]+?(?=})
Replace with: nothing

Answer 2

You could use

\{print\h+\K[^{}]*\R(?=}end)

Explanation

• \{ Match {
• print\h+ match print and 1+ horizontal whitespace chars
• \K Forget wat is matched so far
• [^{}]*\R Match 0+ times any char except { or } and a newline
• (?=}end) Positive lookahead, assert what is on the right is }end

Regex demo

In the replacement use an empty string.
