Is this your html, or are you scraping someone else’s html?

If it’s yours, organize your html differently… if you know you want to  
be processing a section at a time, wrap those sections with an  
identifiable container, then scope your searches by the container.

### blah
- a
- b

### blah2
- c
- d

(doc/“div”).each do |dv|  
this\_h3 = (dv/“h3”)  
if this\_h3.inner\_html == “blah2”  
(dv/“li”).each do |li|  
puts li.inner\_html  
end  
end  
end

emits just c, and d

If its someone else’s html in that format, you’ll probably have to go  
elem by elem for the whole doc with state machine-ish code to track what  
you’ve seen previously since there doesn’t seem to be any real ‘path’ to  
the li’s per h3.

Your html is still flat, so you have to work with the patterns that you  
see.  
You have:  
span  
li  
li  
li  
span  
li  
li  
li  
etc…

An ugly, brute force, one case solution is to:

read the page with Hpricot  
remove the header  
convert it to a simple string representation  
stick your opening tag ‘’ at the head  
stick your closing tag and a div end ‘’ at the tail  
change all ‘’ to ‘

’  
doctor up the new head from ‘

’ to just ‘
’  
re-create your Hproicot doc from the modified string

which takes about 8 lines of code.

YMMV

Please don’t top post, it annoys readers on this list and makes it  
less likely that you will get help.

I have not used hpricot but if I were in your situation the first  
thing I would do is carefully look through the documentation for  
hpricot. Have you done that?
