    See join for joining array elements into a string.

    See map for converting array elements into other.

    Basically, your conversion will look like this:

    my @array = qw(balack white green red); my @tagged_array = map { ... } @array; my $result = join ... @tagged_array; print $result;

    Of course, I've left out the interesting parts, but as you don't show the code you've written, I can't help you more.

    join ", ", map "<tag>$_</tag>", @array;

    For reference, see the documentation of join and map.

    foreach (@array) { $_= '<tag>' . $_ . '</tag>' }
    or with map and creation of a new array
    my @newarray= map { '<tag>' . $_ . '</tag>' } @array;

    UPDATE: misread your question. Should you ever need the tags in the array itself, this would be the answer ;-)

    Do you like XML?

    use XML::Simple; my @array = qw(balack white green red); print XMLout(\@array, RootName => undef, NoIndent => 1); __OUTPUT__ <anon>balack</anon><anon>white</anon><anon>green</anon><anon>red</anon +>
