Notepad++ regex replace named groups

Question

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

100. 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<n1>, ${n1} in replace or maybe \k{n1},\g{n1} but none seems to work in np++. – Schoolmistress

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) – Eclogite

\1 \2 ... working fine in simple samles, but in this case it dosent work (you can try) – Rois

In official help np++ I found what I need but it doesnt work Details here docs.notepad-plus-plus.org/index.php/Regular_Expressions – Rois

I cannot get this regex working at regex101.com – Warms

regex101.com is a really powerful regex platform. The explanation for the regex is pooooooooowerful! – Warms

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.

@Warms Which result you are expect to get? – Rois

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

Answer 1

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

And in replacement: $+{groupname}

Kuchen

ensure you selected "Match case" and "Regular expression" in the Replace tab. – Warms

@Warms I do not need Match case. Question was only about named groups which in official notepad++ documentation described incorrect. – Rois

@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 – Womera
