Ruby XML to JSON Converter?

If you wish to keep all attributes I recommend cobravsmongoose http://cobravsmongoose.rubyforge.org/ which uses the badgerfish convention.

<alice sid="4"><bob sid="1">charlie</bob><bob sid="2">david</bob></alice>

becomes:

{"alice":{"@sid":"4","bob":[{"$":"charlie","@sid":"1"},{"$":"david","@sid":"2"}]}}

code:

require 'rubygems'
require 'cobravsmongoose'
require 'json'
xml = '<alice sid="4"><bob sid="1">charlie</bob><bob sid="2">david</bob></alice>'
puts CobraVsMongoose.xml_to_hash(xml).to_json

I'd use Crack, a simple XML and JSON parser.

require "rubygems"
require "crack"
require "json"

myXML  = Crack::XML.parse(File.read("my.xml"))
myJSON = myXML.to_json

A simple trick:

First you need to gem install json, then when using Rails you can do:

require 'json'
require 'active_support/core_ext'
Hash.from_xml('<variable type="product_code">5</variable>').to_json #=> "{\"variable\":\"5\"}"

If you are not using Rails, then you can gem install activesupport, require it and things should work smoothly.

Example:

require 'json'
require 'net/http'
require 'active_support/core_ext/hash'
s = Net::HTTP.get_response(URI.parse('https://stackoverflow.com/feeds/tag/ruby/')).body
puts Hash.from_xml(s).to_json
