Your spec is rather ambiguous, but I think this will do what you asked for (in that it mimics the output):
Find what : (?-s)^(.*$\R)^(EN)$
Replace with : $1New text $1$2
☑ Regular Expression
Make sure you’re on the Find in Files tab
Find details:
(?-s) = make sure . does not match EOL characters (this will ensure that the next parenthetical will only match one line’s worth
() = Everything inside parentheses gets put into the next $# variable
^ = matches the beginning of a line
$ = matches the end of a line
\R = matches the EOL character sequence (whether it’s a linux LF or windows CR+LF or old mac CR)
^(.*$\R) = combining concepts above: match all the text between the start and end of line, plus the EOL sequence, and store it all in $1
^(EN)$ = match the entire line matching EN, and store EN in $2
Replace details:
$1: quote the values in $1, so it will be the fifth line and its new-line sequence
new text $1: add “New text”, followed by a space and the full contents of the fifth line (including its newline)
$2: quote the EN
P.S. :
(paraphrasing @guy038, the forum’s regex guru, who compiled these great regex resources, but hasn’t shared them in this thread yet):
Here is a good starting point for NPP users unfamiliar with regular expression concepts and syntax:
http://docs.notepad-plus-plus.org/index.php/Regular_Expressions
Modern Notepad++ (since v6.0) uses the Boost C++ Regex library, v1.55.0 (similar to the Perl Regular Common Expressions (PRCE), v5.8):
