require 'rubygems'
require 'nokogiri'

doc = Nokogiri::HTML(DATA.read)
fruits = doc.xpath('//br/../text()').map { |text| text.content.strip }
p fruits

I'm not familiar with nokogiri, but are you trying to find all the children of any element that contains a <br/>? If so, then try:

//*[br]/node()

In any case, using text() will only match text nodes, and not any sibling elements, which may or may not be what you want. If you actually only want text nodes, then
