如何在Ruby中将JSON转换为XML? [英] How can I convert JSON to XML in Ruby?

问题描述

有没有办法在Ruby中将JSON转换为XML?

Is there any way to convert JSON to XML in Ruby?

推荐答案

require 'active_support' #for to_xml() 'gem install activesupport' use the 2.3 branch
require 'json' #part of ruby 1.9 but otherwise 'gem install json'

my_json = "{\"test\":\"b\"}"
my_xml = JSON.parse(my_json).to_xml(:root => :my_root)

还要注意to_xml的根参数.如果您不指定根，它将使用单词"hash"作为根，看起来不太好.

Also note the root argument of to_xml. If you don't specify a root it'll use the word 'hash' as the root which isn't very nice to look at.
