After successive refinements, this looks better indeed. I will try this to morrow.

I go straight from odt to EPUB. I just tweak the EPUB a little after converting, but most of the work is done without touching directly any html file.

I am a Linux user, but I see now which kind of tool can do it. My idea was to add to our existing EPUB converting program a kind of editable super macro (the user could insert or modify any Regex inside). But, if the user needs Power Grep to use it, it would be a self-defeating purpose. On the other hand, if Power Grep can help me prepare this kind of super macro which later could be used without it, as a kind of program, yes it would be worthwhile.
