[Zope] Read a file

Hi I want to read the contents of a file.I have a form where user uploads doc files.I want to give preview of that file after user uploads the file.What I am thinking is I will read the contents of that file and store it in another file with content-type text/html so that it can be displayed in the browser.But I have no idea how to read the contents of a file stored in zodb .Can someone help? __________________________________ Celebrate Yahoo!'s 10th Birthday!
