... and yet another way to do it, this time using a subroutine instead of putting everything inside a single RegEx (added readability for those who like that kinda coding style).

my  @aTests = (<DATA>);
    for (@aTests){
        s/\]|\[//gm;        ### strip off sq brackets
        s/^\s*|\s*$//gm;    ### trim whitespace

        ### put fields into array ref and spit out href
        print   &spitHref([split /\s*\|\s*/,$_]);
        print   "\n-----\n";
    }

sub spitHref(){
    my  $aFields    = shift || die"required array ref missing";
    my  $iFlds      = scalar @{$aFields};
    return
    ($iFlds == 0) ? "ERROR: bad data"
    : ($iFlds == 1) ? qq^<a href="$aFields->[0]">$aFields->[0]</a>^
    : ($iFlds == 2) ? qq^<a href="$aFields->[0]">$aFields->[1]</a>^
    : ($iFlds == 3) ? qq^<a href="$aFields->[0]" target="$aFields->[2]
+">$aFields->[1]</a>^
    : 'ERROR: unexpected data'
    ;
}###end_sub
