Help getting started with hpricot

I haven’t really understood hpricot yet, but i s’ppose it puts the
filtered text into some kind of hash/array? What i wanna to is compare
multiple html-sources, for example:

First source

Monday 5 Wednesday 9 ---

Second source

Monday 7 Wednesday 7 ---

I wanna be able to filter, and via my rubyapp select “Monday”, and see
that source two is better than all the other sources, becouse 7 > 5 and
3 or whatever the third source has in store for monday.

Thanks in advance!
