By class, I'm assuming you mean meta_type, yes?

First off, you can do this:

<dtml-in "objectValues('Folder')">
    <dtml-var title_or_id>
</dtml-in>

If all you want are the objects of a given meta type.  The argument passed 
to objectValues can also be a list of meta_types.

If you actually want to branch on an object's meta type, try:

<dtml-in objectValues prefix=my>
    <dtml-if "my_item.meta_type == 'Folder'">
</dtml-in>

HTH,
