No problem. I don't know much about Isilo, but hopefully you can make something of the sitescooper .site files. I would recommend using sitescooper - it's old and difficult to set up in my experience, but it does an excellent job. I spent much of my last summer (one year ago - I'm in the Southern Hemisphere) setting it up and writing site files and I've had excellent content to my Palm ever since, just by pushing a couple of buttons every day. The annoying thing is when WP/NYT/whatever decides to redesign its site (grrr!). But maybe Isilo can do the same thing equally well, I've just never investigated it.
Again, good luck and Merry Christmas
