Ruby XML to JSON Converter?

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/')).bodyputs Hash.from_xml(s).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

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
