Bookmark lines regex

Tanja Corell

Hi.

I need to bookmark all lines with the following:

/s/2593740/1/

The number in bold changes from line to line.

I’ve tried with:

/s/[0-9]/1/ but that doesn’t seem to work.

solution:

source text:

aaa/s/2593740/1/xxx
bbb/s/3452352/1/xxx
ccc/s/463345/1/xxx
ddd/a/2236674/1/xxx
eee/s/67894775679/1/xxx
fff/s/8078/3/xxx

mark search regex:

/s/(.*?)/1/

result:

(bookmarked) aaa/s/2593740/1/xxx
(bookmarked) bbb/s/3452352/1/xxx
(bookmarked) ccc/s/463345/1/xxx
             ddd/a/2236674/1/xxx
(bookmarked) eee/s/67894775679/1/xxx
             fff/s/8078/3/xxx

[0-9] matches any one character in the set 0, 1, 2, …, 9.
[0-9]+ matches one or more of the characters in the set 0, 1, 2, …, 9.

That should explain why /s/[0-9]/1/ did not work for you.

Thanks that did the trick.Does the regex work in any program that needs a regular expression or just in Notepad ++?

it works on any similar regex engine eg php functions like preg_match_all()

but you have to make sure to escape all characters that would be interpreted as a regex pattern part instead of a character you are searching for

eg: if you use / as a regex start and end delimiter character, you have to write \/ for every slash you want to find to make regex search for the character /

so /s/[0-9]+/1/ in a php example where you use / as regex start-end delimiters it has to be rewritten to:

preg_match_all("/\/s\/[0-9]+\/1\//ms", $source_text, $matches_array);

or you can use a different delimiter character:

preg_match_all("#/s/[0-9]+/1/#ms", $source_text, $matches_array);

then if you search for the physical character # you’ll have to write \#
