    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?
