code I use to sync my posts up with app.net versions

gistfile1.rb

require "nokogiri"
require "open-uri"

data = Nokogiri::XML(open("https://alpha-api.app.net/feed/rss/users/49269/posts"))
items = data.xpath("//item//atom:link/@href", "atom" => "http://www.w3.org/2005/Atom").map(&:to_s).map {|i| i.split("/").last.to_i }.zip(data.xpath("//item//link").map(&:text))

items.each do |i|
   p = Post.find(i[0])
   unless p.properties.has_key?('appdotnet')
      p.properties['appdotnet'] = i[1]
      p.save
   end
end
