Thats no way complicated. The "list" is the word python people use
instead of "array" :-) If you note for your checkbox name
a name and :list, zope automatically converts all selected entrys into
a list containing the selected entrys. If you dont write :list, it does
it anyway if there is more then one selected. To be save, use "ids:list"
so the list is called ids. (refering to the example below)

As mentioned, you dont have to delete item by item if they are stored 
in Zope as objects. you only need to pass it to the manage_delObjects
method of the folder:

<dtml-call expr="yourfolder_with_items.manage_delObjects(ids)">

(schould work. Untested)

If you have your items in a sql database, you may want to ilterate like
this:

<dtml-in ids>
  <dtml-call
expr="dosomethingtodelete(itemtodelete=_['sequence-item'])">
</dtml-in>

Tino
