When I cross-post from other sites to this blog, I need to reformat the HTML to Dokuwiki syntax. I wrote a quick script to make that process easier. The script is by no means complete, but others may find it useful. You can get it here: Convert HTML to DokuWiki (Ruby Script)
Update 2013: If you use this, please exercise caution. It wasn’t fully featured when I wrote it, and it may well be out of date now.
