Green Button Data

Green Button Data is a Ruby gem that can quickly parse the Green Button data standard. It uses an event-driven SAX parser which does not build the entire DOM in memory.

Getting Started

Add the Green Button Data gem to your Gemfile:

gem 'green-button-data'

Then run Bundler:

$ bundle

Usage

Almost all of the functionality for parsing data is wrapped in the GreenButtonData::Feed class.

To parse a Green Button Atom feed, simply call the parse method and pass in the entire XML document:

require 'green-button-data'

xml_text = File.read "#{File.dirname __FILE__}/gb_example_interval_block.xml"
data = GreenButtonData::Feed.parse xml_text

You can then access the data like this:

# Print all the interval readings from the feed
data.entries.each do |entry|
  p "Entry: #{entry.title}"
  entry.content.interval_block.interval_readings.each do |reading|
    time_period = reading.time_period
    p "[#{time_period.starts_at} - #{time_period.ends_at}]: #{reading.value}"
  end
end
