[Zope] Calling DTML Document from python script

[Laurent Duchesne]

I got an object 'file' witch contains a DTML Document object.
When I try to call it from a pythton script like this :
	print file()
I get the error :
	Error Type: KeyError
	Error Value: standard_html_header
 
So what I need to do is to print out the DTML document without it's header 
and footer (<dtml-var standard_html_header> and <dtml-var 
standard_html_footer>) and still that it's content get executed (all other 
dtml-var gets resolved)

Anyone knows how to do that and maybe what parameter I have to pass to the 
print file(...) function?
