I need to query if one folder has sub-folders in it or not. You can use the "tpValues" method. It is used by the "tree" tag to determine whether or not the node can be expanded.

I want to manipulate every object returned by the "tree" tag like this

<dtml-tree bla bla ..>

<dtml-let myObject="tree object">

<dtml-var myObject.someProperty_or_method_or_something>

</dtml-let>

</dtml-tree> A look at the tree tag code in "TreeDisplay.TreeTag" convinced me, that (unlike "dtml-in") "dtml-tree" does not provide a direct reference to the rendered object. You may (or may not) have luck and the rendered object has a "this" method (many Zope objects have). Then you can use "this()" as a reference to the object. You must take care for cases, when "this" does not exist.

I think, "dtml-tree" should define "tree-item" in analogy to the "dtml-in"'s "sequence-item". This is a low priority feature request, I will put into the locator, if I do not forget it. Dieter
