Hi,
/(\d+),(\d+)(;(\d+),(\d+))*/
This regexp matches are:
0: (5,1;5,7;3,2)
1: (5)
2: (1)
3: (;3,2)
4: (3)
5: (2)
My question is why ;5,7 is not matched ?
Thanks,
Mickael.

Because it matches ;5,7 first and then overwrites $3,$4 & $5 with ;3,2
which
matches based on the ‘*’

And is there a way to keep previous matching ?

What about tackling it from a completely different angle
s = “5,1;5,7;3,2”
pairs = s.split(‘;’) #=> [“5,1”, “5,7”, “3,2”]
pairs.each do |pair|
pair.split(‘,’) #=> [“5”, “1”] etc
end

irb> re = /(\d+),(\d+)(;(\d+),(\d+))/
=> /(\d+),(\d+)(;(\d+),(\d+))/
irb> s = “5,1;5,7;3,2”
=> “5,1;5,7;3,2”
irb> s.match(re).captures
=> [“5”, “1”, “;3,2”, “3”, “2”]
You can wrap another set of parentheses in there:
irb> re = /(\d+),(\d+)((;(\d+),(\d+)))/
=> /(\d+),(\d+)((;(\d+),(\d+)))/
irb> s.match(re).captures
=> [“5”, “1”, “;5,7;3,2”, “;3,2”, “3”, “2”]
But in addition to Andrew’s split, you could use String#scan
irb> s.scan(/(\d+),(\d+)/)
=> [[“5”, “1”], [“5”, “7”], [“3”, “2”]]
It all depends on what you’re trying to accomplish.

Sure, that’s what I’ve just done
Just wondering.
Thanks anyway.
