Regex: match and replace on a date

Question

I'd like to convert the date separators in a date.

So, from 11.11.2009 -> 11-11-2009

Could someone help me do that with a regex?

Answer 1

In Perl:

s/\./\-/g

Answer 2

my_date = my_date.replace(/\./g, '-');

Answer 3

you mean '11.11.2009'.replace(/\./g, '-')
