Regex excluding a specific characters

I have following tags available in git.

popup/0.0.998
popup/14.0.999
popup/54.33.99
popup/20160729/0.0.624
popup/20160730/1.55.624
popup/20160930/99.44.783

From these tags I want only following and exclude others tags. That is I want only tags popup/natural_number.natural_number.natural_number has this format.

popup/0.0.998
popup/14.0.999
popup/54.33.99

I used following command but it is still giving following tags -

Command used:git tag -l 'popup/[0-9]*\.[0-9]*\.[0-9]*'

Giving all tags:

popup/0.0.528
popup/140.42.409
popup/54.323.726
popup/20160729/0.0.624
popup/20160730/1.55.624
popup/20160930/99.44.183

Kindly suggest, How can I achieve this.

git tag doesn't take a regular expression and the reason that it returns something is because it accepts filename expansions or globbing. You could use grep instead:

git tag -l | grep -P '^popup/\d+\.\d+\.\d+$'

You probably have to escape backslashes:

popup/[0-9]*\\.[0-9]*\\.[0-9]*

I've tested with grep and it worked:

$ cat tags
popup/0.0.998
popup/14.0.999
popup/54.33.99
popup/20160729/0.0.624
popup/20160730/1.55.624
popup/20160930/99.44.783
$ cat tags | grep popup/[0-9]*\\.[0-9]*\\.[0-9]*
popup/0.0.998
popup/14.0.999
popup/54.33.99
