Regular Expression Validation for Complex Passwords

Hi All,

Could anyone provide me with the regexp validation for the following string criterion:

Must be min of 10 characters; and
Must include 3 of the 4 character types -
    Upper case letters
    Lower case letters
    special characters

Many thanks,

Nilang Shah has an example of almost exactly your question. He expects all four types to be present.

You can extend this expression using the 'or'-sign (|) to combine the separate expressions that include 3 of the 4 types.

Something like this will do :)
