I took at look at scRUBYt, looked nice, but I ended up just using hpricot - fast, and pretty easy. I would just have one screen with the site with firebug open, and grab the xpath expressions from it, slap them in a ruby string and then put in place holders for the parameters. Only minutes of work.
