I currently have a very specific RegEx for use in identifying dates as yyyy/mm/dd
[0-9]{4}\/[0-9]{2}\/[0-9]{2}
Which works fine for my needs when identifying dates in text but I was wondering how I can use a similar RegEx to match everything that is not a date
The current one when using Date 1980/01/01 will match 1980/01/01
But now I need it when using Date 1980/01/01 to match Date
UPDATE
To better illustrate what I am trying to achieve I have a very basic RegEx that matches all standard letters
[a-zA-Z]
When using abcDEF123 it will match abcDEF
The inversion of it would be
[^a-zA-Z]
When using abcDEF123 it will match 123 (anything that is not a standard letter)
>Solution :
/(?<=What you don’t want)(What you want)
A positive lookbehind

OR
(What you want)(?<=What you don’t want)/
positive lookahead.
(?<=[0-9]{4}\/[0-9]{2}\/[0-9]{2})(.)+|(.)+(?=[0-9]{4}\/[0-9]{2}\/[0-9]{2})
