Notepad++ regex replace named groups

Question

I try replace author Full name with article title I have a list of articles, similar like this:

Albershein P., Nevis D. J. A method for analysis of sugars in plant cell wall polysaccharides by gasliquid chromatography // J. Carbohydrate Research. – 1967. – Vol. 5, № 3. – Р. 340–345.

And I have Regex for it

(?'n1'^\d{3}\. )(?'n2'(?:(?:[A-ZА-Я][-a-zćа-я ]+)?([A-ZА-Я][-a-zćа-я]+\xA0[A-ZА-Я]\.(?:\xA0[A-ZА-Я]\.){0,2}\,?)(?: \[et al\])? ?)+)(?'n3' [^\/]+[\/]{2})

but replace like

\k{n1}

or

\k'n1'

doesnt work

we try this in perl but have the same result

Try just numeric group index `\1` or `$1`. Groupname would be [\g](https://regex101.com/r/mR0nU9/1), `${n1}` in replace or maybe `\k{n1}`,`\g{n1}` but none seems to work in np++. — bobble bubble, Nov 10 '15 at 15:49
In Perl you might try `$+{name}` on the replacement side, but it should be in the form of eval `s///eg` (not sure about the eval) — , Nov 10 '15 at 16:34
\1 \2 ... working fine in simple samles, but in this case it dosent work (you can try) — Victor Dronov, Nov 11 '15 at 10:27
In official help np++ I found what I need but it doesnt work Details here http://docs.notepad-plus-plus.org/index.php/Regular_Expressions — Victor Dronov, Nov 11 '15 at 10:29
regex101.com is a really powerful regex platform. The explanation for the regex is pooooooooowerful! — Decula, Oct 23 '18 at 19:13
how should I use regex to replace this reference? [23] D. Spina, M.-H. Peetz, and M. de Rijke. Active learning for entity filtering in microblog streams.

**Regex:** `^\[?(?\d{1,3}\.?)\]? (?((and )?(-?[A-Z]\. ?)+(de )?[A-Z][a-Z]+[,.] )+)(?.+)` **Replace with:** `$+{n1} $+{n3} // $+{n2}` **Output:** `23 Active learning for entity filtering in microblog streams.

Try using in regex (?<groupname>something to match)

And in replacement: $+{groupname}

ensure you selected "Match case" and "Regular expression" in the Replace tab. – Decula Oct 23 '18 at 18:48

@Decula I do not need Match case. Question was only about named groups which in official notepad++ documentation described incorrect. – Victor Dronov Nov 07 '18 at 12:05
@Jakub Binkowski Can you please elaborate on this usage? I can't find it in the documentation. I noticed that I can use a single `{groupname}` for conditionals, but I have to prefix it with `$+` if I want to use the content in replacement – George Menoutis Mar 10 '22 at 08:28
