[Zope] extract complete filepath from HTML input file-tag

[Andrei Belitski]

Hi!
I need to extract the complete path of an <input type=file name="my_file"> 
because if a PDF file should be uploaded, I 
call a python script which uses the linux pdftotext command (which should to 
know where the file is) to convert the file to plain text and pass this plain 
text to ZCatalog indexing system to have stored in zope the searchible 
content of a PDF too.

The only thing I get from REQUEST['my_file'].filename is the file name 
without the path 'cause I work under linux

May be you have some other tip for me?

I would appreciate your help
greetings Andrei
