Hi Tobia,
Me again...
I now that you understood what I said, but only for clarify, all the steps
that I need to develop are:
1. Read a template file in any type of Office (like .DOC, .PPT and .XLS-->
for the last one, I got success with jxls.sourceforge.net);
2. When I find some key (someword between delimiters like "[" and "]" or in
expression language like ${xyz} --> the last one has been used in tht jXLS
project), I select for that key in a database and get the correspondent
value;
3. With all the values found, a new file is generated changing the keys by
the values, with the same format of the original file (template file).
In the following, I comment

You should check whether those file formats store strings in plain text,

Yeah, I took a look at .DOC, .PPT and .XLS file type and it seems that all
that I have been typed into .DOC and .PPT files are in text plain, but not
in .XLS type.

Yeah man! That's point for me now!
My client told me that I can consider the usage of Office 2003 for the
users. So, all the office types are XML-based, right?
Now, I have to know how to do it with Cocoon.
Could you give me some examples?

Yes, the image insertion. Sometimes, I have to change a text key by an
image. So, if I have a file create by the Microsoft Office, that is
XML-based, how could I change a text by an image? May I have to know
something about the spec of file to know how to change it or not?
If anybody could help with these issues, I thank you in advance!
Luiz
Just a few ideas.
