Filtering URL addresses

[pp2014]

I have a field in the dataset called webpage:

It has values as follows:

www.abc.com/about
www.abc.com/about-afib
www.abc.com/about/activations
www.abc.com/home/
www.abc.com/mobile
www.mobileabc.com/xyz.php

I want the following output:

www.abc.com/about
www.abc.com/home/
www.abc.com/mobile

Not sure what the "question" is here or what the logic is.  There a many ways to do that: if _n_ in (1,4,5) then output;, or if scan(<text),2,"/") in ("about","home","mobile") then output; etc.

data x;
input x $80.;
y=scan(x,1,'/')||'/'||scan(x,2,'.','kad');
if findc(scan(x,-1,'/'),'.') then call missing(y);
cards;
www.abc.com/about
www.abc.com/about-afib
www.abc.com/about/activations
www.abc.com/home/
www.abc.com/mobile
www.mobileabc.com/xyz.php
