There is the "branches_expr" attribute to "dtml-tree".

You can use it like this:

    <dtml-tree ... branches_expr="yourDTMLmethod(_vars.None,_vars)">
      ....
    </dtml-tree>

Now, with PythonScripts, it is worth to learn Python (it was before,
but now it is even more rewarding). You should not need more
than a few days.

    <dtml-return "any of your favorite lists">
