Bookmark consecutive lines that have same specific value

Question

I have a list like following:

ABC
GFGFG
/////////////////////////
ggtrgrh
htrhrth
nbtnyumjyumu
myuuykukyyuk
/////////////////////////
/////////////////////////
AAAAA
AAAAAAAAAAA
RET5t4yy
HTH^565y56y
/////////////////////////
tertet
/////////////////////////
/////////////////////////
/////////////////////////

now I want to bookmark consecutive lines that have /////////////////////////
this mean in above list only three last lines and lines between myuuykukyyuk and AAAAA must select by regex.
I tried following regex but not working for me:

(?:.*/{25,}\r?\n?){3}
^/*/{25,}$

where is my regex problem?

I want to only match two or more lines that only contain 25 or more slashes

Answer 1

You can use

^/{25,}(?:\R/{25,})+$

See the regex demo.

Details:

• ^ - start of a line
• /{25,} - twenty-five or more forward slashes
• (?:\R/{25,})+ - one or more repetitions of
  • \R - any line break sequence
  • /{25,} - twenty-five or more forward slashes
• $ - end of a line

See the screenshot with demo and settings:
