can't open word document after string replacements
Hi there,
I have a word document containing pictures and text. This documents
holds several 'ABCDEF' strings which serve as a placeholder for names.
Now I want to replace these occurences with names in a list (members). I
open both input and output file in binary mode and do the
transformation. However, I can't open the resulting file, Word just
telling that there was an error. Does anybody what I am doing wrong?
Oh, and is this approach pythonic anyway? (I have a strong Java background.)

for line in doc:

try:
line = line.replace('ABCDEF', members[counter], 1)
docout.write(line)

The Word document format probably contains some length information about paragraphs etc. If you change a string to another one of a different length, this length information will no longer match the data and the document structure will be hosed. Possible solutions: 1. Use OLE automation (in the python win32 package) to open the file in Word and use Word search and replace. Your script could then directly print the document, which you probably have to do anyway. 2. Export the template document to RTF. This is a text format and can be more easily manipulated with Python. for line in doc: I don't think that what you get here is actually a line of you document. Due to the binary nature of the format, it is an arbitrary chunk. Daniel -- http://mail.python.org/mailman/listinfo/python-list

Do you know that MS Word already provides this kind of features ?

Hand-editing a non-documented binary format may lead to undesirable
results...
Oh, and is this approach pythonic anyway?
The pythonic approach is usually to start looking for existing
solutions... In this case, using Word's builtin features and Python/COM
integration would be a better choice IMHO.

Errr I wouldn't even attempt to do this; how do you know each
'line' isn't going to be split arbitarily, and that 'ABCDEF' doesn't
happen to be part of an image. As you've noted, this is binary data so
you can't assume anything about it. Doing it this way is a Bad Idea
(tm).
If you want to do something like this, why not use templated HTML, or
possibly templated PDFs? Or heaven forbid, Word's mail-merge facility?
(I think MS Office documents are effectively self-contained file
systems, so there is probably some module out there which can
read/write them).

Re: can't open word document after string replacements
Thank you all for your comments. I ended up saving the word document in XML and then using (a slightly modified version of) my script of the OP. For those interested, there was also a problem with encodings. Regards, antoine -- http://mail.python.org/mailman/listinfo/python-list

I don't know how it's named in english, but in french it's (well - it

DOC files contain housekeeping info which becomes inconsistent if you
change text. Possibly you can exchange stuff of equal length but that
wouldn't serve your purpose. RTF files let you do substitutions and they
save a lot of space too. But I kind of doubt whether RTF files can
contain pictures.
