[Zope] Uploaded File Interaction

[Diego Rodrigo Neufert]

I'm doing a ZClass based product and want to change some lines in a uploaded 
file....
How can I interact with this file and see their content?
<dtml-var "REQUEST.form['attched_file']"> doesnt work.... any ideias?
I want to do something like while <FILE>: in perl....

Thanks!
