If you turn it into a document data field, you can use $split to chop
it up. Say you store the above as "Apparel &
Accessories/Clothing/...", you could have:

categories: field=categories

$list{$map{$split{/, $field{categories}},<span
class='category'>$html{$_}</span>}, -&gt; }

If you stored tokens instead of strings you could turn them into links
as well by using a $setmap{}. (You can also localize that way, if you
need to.)
