Yep; in theory you could do something like:
soup.fetch("table")[5].fetch("tr")[2].fetch("td")[1].string That would get you the contents of the cell on the 3rd row down and 2rd column across, on the fifth table on the page. The fetch method works with any tag.
(The .string at the end gets the contents of the tag, just as ['href'] gets the href attribute of the tag)
