This mainly depends on the file format. If you can be 100% sure that this, and only this is the way lines will be presented, then you can do the following:
my @output;
foreach my $line (@lines) {
my @split = split ' ', $line; #split by whitespace
pop @split if $split[0] eq '*'; #getting rid of leading *
$split[0] =~ s/\.//g #remove the dots from the element
push @output, $split[0] . ' ' . $split[3];
}
Otherwise, you'll need to do a foreach on each of @split's elements, match them to a pattern and use those that you need.
