ruby + XPath

To document an annoying example…

require 'rexml/document'
include REXML #namespace convenience
doc = Document.new File.read("chiquita_shipments.xml")
doc.elements.each("//fruits/fruit/color") do |el| 
  puts el.parent if el.texts[0].to_s == "yellow"
end

Let’s say chiquita_shipments.xml looks like…

  
    banana
    yellow
    no
