CirrostratusParameter Value - Regular Expression
I want to restrict parameter value to accept date only, is below Regular Expression will work? ^([0-2][0-9]|(3)[0-1])(\/)(((0)[0-9])|((1)[0-2]))(\/)\d{4}$
I found this regex, fits in the 254 character limit and checks:
- valid dates
- if leap year, then 29.2. is also valid
(^(((0[1-9]|1[0-9]|2[0-8])[\/](0[1-9]|1[012]))|((29|30|31)[\/](0[13578]|1[02]))|((29|30)[\/](0[4,6,9]|11)))[\/](19|[2-9][0-9])\d\d$)|(^29[\/]02[\/](19|[2-9][0-9])(00|04|08|12|16|20|24|28|32|36|40|44|48|52|56|60|64|68|72|76|80|84|88|92|96)$)

Cirrostratusdear Daniel,
the idea is, i want to accept date format only (dd/mm/yyyy) in this parameter and block others value like text and so on. so do i have to use the mentioned regex (your regex) ?
one more thing, i can not use the above regex because it exceed the limit . how can i re-write the regex to accept dd/mm/yyyy ?
