[Zope] Reading File Contents

[Cliff Ford]

That last solution was a bit long-winded. Try this python script (put
theText in the parameter list):

lines = string.split(theText, '\n')
for line in lines:
     (subject, email) = string.split(line, ',')
     print 'Subject=%s, Email=%s' % (subject, email)

return printed

and call it like this:

<dtml-var expr="myList(_.getitem('file_name', 1))">
