Regex to get date from string

Question

I need a regular expression to get date out of the following String

anything-2011.01.17-16.50.19.xml

Is this a correct one

^\\         


        

Answer 1

This here is checking the format YYYY.MM.DD-HH.MM.SS

^(.*?)-(\d{4}(?:\.\d{2}){2}-\d{2}(?:\.\d{2}){2})\.xml$

But it does not verify if the date or the time is a valid value.

Online check on regexr.
