Fast XML to Ruby Hash converter
XmlHasher is available through Rubygems and can be installed via:
$ gem install xmlhasher
or add it to your Gemfile like this:
gem 'xmlhasher'
See CHANGELOG.md
require 'xmlhasher'
# XmlHasher global configuration
#
# snakecase - convert all keys to snake case notation
# ignore_namespaces - remove XML namespaces
# string_keys - represent keys as Strings instead of Symbols
#
# here is default configuration
XmlHasher.configure do |config|
config.snakecase = true
config.ignore_namespaces = true
config.string_keys = false
end
# alternatively, specify configuration options when instantiating a Parser
parser = XmlHasher::Parser.new(
:snakecase => true,
:ignore_namespaces => true,
:string_keys => false
)
# by default, XmlHasher will convert all keys to symbols. If you want all keys to be Strings, set :string_keys option to 'true'
# parse XML file
XmlHasher.parse(File.new('/path/to/my/file.xml'))
# parse XML string
XmlHasher.parse("<tag1><tag2>content</tag2></tag1>")
# => {:tag1=>{:tag2=>"content"}}How fast is it? Try it for yourself rake benchmark
