regex - dash symbol match

Question

I'm trying to match the "-" symbol

https://regex101.com/r/7NuWBy/1

([0-9]+) (Cat) · ([0-9]+) (Dog) · ([0-9]+) (Fish)

This is the text

134 Cat · 13 Dog · — Fish
14 Cat · 133 Dog · 1 Fish
124 Cat · 1333 Dog · 32 Fish

Answer 1

First, you should not use a . directly instead use \.
because a . means any character except a newline \n
so the correct regex would be:

([0-9]+|-) (Cat) \· ([0-9]+|-) (Dog) \· ([0-9]+|-) (Fish)

Answer 2

Converting my comment to answer so that solution is easy to find for future visitors.

Your desired regex must include hyphen also since you want to match substrings that include hyphens as well. Your intended regex would be:

([0-9—]+) (Cat) \· ([0-9—]+) (Dog) \· ([0-9—]+) (Fish)

A dot has a special meaning and it must also be escaped to avoid matching just any character.
