BG : I guess I need to walk the whole tree. I came across such problem
when using enlive to scrape a news page. enlive creates a hash map of
entire html and then you can pull out stuff using css style selectors.
there were things i couldn't do using the supplied selector methods
and i felt the need to walk the tree myself. i created the dining-
table to understand how to transform a hash map.
