Thanks, but it does not work as it says I am unauthorized in this context (valid only only in an external script). However I uploaded the file through a form and had no problem (readlines() passed through without any warning) : file = REQUEST.form['file_attachment'] for line in file.readlines(): .... Which is kind of strange. The issue is, I would like to work on a very big file and there may be problems with this. I would like to to access the file as it is already stored in the ZODB. Any other idea? Pierre Godefroy Bories v. dem Bussche wrote:

You might want to try something like

from StringIO import StringIO data = StringIO(str(getattr(container,'marco').data))

Well... 1. Don't serve large stuff from ZODB if you can avoid it. 2. If you want to parse *any* ZODB content, do this: --- data = getattr(context, my_obj_name) for line in data.readlines(): # do stuff --- HTH, Dylan

Pierre, The file "marco" is, presumably, a Zope ZOOB file. Your variable data is a string containing that files content. You can split it into lines using lines = data.split('\n') and then iterate through the lines. On Sun, 30 Nov 2003, Fernando Martins wrote:

I get a readlines : attribute error

Could anyone help me?

Python scripts are very limited (by design) regarding available functions and modules. Check the Zope book 2.6 (sorry don't remember which section).

The recomended solution is to use External methods (if you have access to the zope instalation). Quite simple: create a .py file with your functions in the folder External and the link to the function you want from the zope ZMI. Then you can use this (external) function as any other zope available function.
