Java - Regular Expression opposite

Hi All,

i had a regular expression which filters the date field MM/dd/yyyy i.e., ^(0[1-9]|1[012])[- //.](0[1-9]|[12][0-9]|3[01])[- //.](19|20)\d\d$. My question is i can filter matching records but i need which are not in this format (i need to fetch the records other than this format). for that i found (^((?!((0[1-9]|1[012])[- //.](0[1-9]|[12][0-9]|3[01])[- //.](19|20)\d\d)).)*$) in searching but it is not working in java scriptella.

please help me on this.

thanks in advance.

Just putting it out there but might it not be easier to use a DateFormatter if you are using java?

In general the negation of ^X$ is ^(?!X$).

Hi requinix,

thanks this is working for me.
Thanks a lot.
