How to extract digits from a String and transform them into an Integer

Question

How to remove space between 2 numbers ? I have a String "1 026 personnes aiment ça" and I would like to get only 1026 (as Integer)

My attempt:

text = "1 026 personnes aiment ça"
# => "1 026 personnes aiment ça"
z = text.split(' ').first
# => "1 026"
z.to_i
# => 1
z.strip
# => "1 026"
z.class
# => String

Answer 1

The #gsub method can replace all non-digit characters in the String and then you can transform it into an Integer with #to_i:

"1 026 personnes aiment ça".gsub(/\D/, "").to_i
#~> 1026

Answer 2

you can try this it`s work for me

(?<=\d) +(?=\d+(?:\s|$))
