i'm replying to myself...
the solution is here http://www.wikimatrix.org/forum/viewtop … d=265#p265
zwiki produce html page that html2wiki can parse to generate dokuwiki code !

The task would be very long if we had to do it by hand on the existing intranet wiki.

So the soluce is to use HTML::WikiConverter perl package with the "dialect" DokuWiki.

Thus we write a perl script that gets the html page, and gives to HTML::WikiConverter::DokuWiki the stuff to do and create our Dokuwiki page.

I'm happy to say that the life of zwiki @work is just a question of a little time
