[Zope] uploading xml files

[garry saddington]

I have a form which uploads an xml file into zope. Is it possible to display 
the contents of this file in a dtml method which is the target of the upload 
form action. I have searched all over for an answer and have come up empty. I 
know this may be simple to some people but at the moment this is blocking my 
further progress with zope. If there is any documentation on this subject 
could someone point me at it please?
regards
