I need to know the regular expressions to pick out the date values (birthday, anniversary, Other).

Any help would be highly appreciated.

Eidt: i just asked to pick out the date values i am able to pick other values. The link given is not helpful for me.

Answer 1

What you had was quite close, but a few changes are required:

(?<strElement>(BDAY)) (:(?<strBDAY>([^\n\r]*)))
              ^    ^  ^            ^        ^ ^

The parts I pointed out above are the either unnecessary (in case of parentheses) or causing a problem.

Change the space to something like \S+ perhaps and remove the extra parens:

(?<strElement>BDAY)\S+:(?<strBDAY>[^\n\r]*)

Without DataTime validation:
