Basic script to parse WordPress XML. Although Nokogiri is the most popular lib for XML in Ruby these days, I've found Hpricot's API to be a lot easier to work with.

import_from_wp.rake

desc 'import from WordPress XML file'
task :import_from_wp => :environment do
  require 'hpricot' 

  doc = Hpricot::XML(File.read('wp-export-file.xml'))

  posts = (doc/:channel/:item)
  posts.each do |post|
    p "Post: #{post.at('link').inner_text}"
  end

  p "Total posts: #{posts.size}"
end
