Problem

I have a statement like this

   <dpl>
   category=Mycenean
   </dpl>

Now some of the pages in the category are subpages so I get a display like this

   * Greek/Mycenean
   * Greek/Mycenean/Texts
   * Greek/Mycenean/Writing
   * Greek/Mycenean/Writing/Syllabary

• Greek/Mycenean
• Greek/Mycenean/Texts
• Greek/Mycenean/Writing
• Greek/Mycenean/Writing/Syllabary

I would like them to appear as an hierarchical listing

   * Greek
   ** Mycenean
   *** Texts
   *** Writing
   **** Syllabary

• Greek
  • Mycenean
    • Texts
    • Writing
      • Syllabary

N.B. That [[Category:Greek]] would have further subpages [[Greek/Writing]], [[Greek/Dialects]] and whatever which shouldn't appear in a listing of category=Mycenean, but [[Greek]] itself should, as the top page in the category=Mycenean hierarchy is itself a subpage of that page.

As for constructing code which translates the current wikitext into the desired one this Perl regex does the trick, except that they don't add the [[Greek]] top node (There would need to be some check to see if the category named in a category= parameter is itself a subcategory and if so add the supercategory/-ies):

s{^\*[ ](\[\[.+?([^/]+)\]\])}{ 
    $l = $1; 
    $c = ($l =~ s#/#/#g); ## Count the number of slashes in the link and add 1.
    $l =~ s#([^/]+)\]\]$#$1\|$1\]\]#;  ## Copy link text
    "\*" x $c  ." ".$l;  ## Print out the right number of asterisks and the link
}egm;

This is the concept. A bit harder of course if done on HTML rather than wikitext.
