At http://wiki.github.com/tenderlove/nokogiri/ you can read on how to
find the nodes you need. I think you’ll need to use xpath.

If you just want to extract some specific text within a specific tag you
should go with what Luis posted.

If you want to extract the whole plain text from a specific area in your
document, not knowing which tags may occur, you can try this:

I do it like this:

puts doc.search(‘p’).map { |e| e.text }
