How to use regular expression to retrieve the specific string in different OS file Path

How to use regular expression in javascript to retrieve the datatime stamp path in different OS

Here's the example.

D:\\deploy\\logs\\uat\\20140929101121\\build1.log

//usr//bin//app1//log//dev//20140929100730//build2.log

//usr//bin//app1//log//dev//20140929100728//build1.log

And I would like to retrieve the string of

you can also try this i used in perl.

use strict;
use warnings;

my $string = qq(D:\\deploy\\logs\\uat\\20140929101121\\build1.log

//usr//bin//app1//log//dev//20140929100730//build2.log

//usr//bin//app1//log//dev//20140929100728//build1.log);

$string =~ s{^(?:.*?)(?:[\\/]*)([0-9]{14})(?:[\\/]*)(?:.*?)$}{$1}igm;

print $string;

The Output: 

20140929101121

20140929100730

20140929100728

(\d+)(?=[\\\/]{2}[^\\\/]*$)

You can try this.This will remove the dependency of having 14 digits.See demo.

In the example data you provided it would be fair to say that you want 14 digits that will be followed by a path separator of either // or \\.

If that is the case then it is as simple as:

(\d{14})(?=[\\/]{2})

This will capture the 14 digit timestamp, where it is followed by either // or \
