.... What I need is, from a dtml method in /news, to get the size of an object (a file, say /news/files/file01.pdf) in /news/files. You know Zope's integrated online help?

There you would find that files have a method "getSize" that returns their size. In the upcoming Zope bock (-> zope.org), you could read that "dtml-with" can be used to access objects in "foreign" contexts: <dtml-with "news.files"> <dtml-var "_.getitem('file01.pdf').getSize()> </dtml-with> or <dtml-var "_.getattr(news.files,'file01.pdf').getSize()"> will do.
