Maybe not tidy but still you can try do the following:
require 'json'
test = JSON.parse(json)
test.each {|k|
p "============================"
full_text = k['full_text'] unless k['full_text'].nil?
urls = k['entities']['urls'] unless k['entities']['urls'].nil?
urls.each {|u|
entities_url = u['url'] unless u['url'].nil?
p "Url: #{entities_url}" }
lang = k['lang'] unless k['lang']
media = k['entities']['media']
extended_media = k['extended_entities']['media'] unless k['extended_entities'].nil?
p "Full text: #{full_text}" unless full_text.nil?
media.each {|u|
p "Media url: #{u['media_url_https']}" unless u['media_url_https'].nil?
} unless media.nil?
extended_media.each {|u|
p "Extended url: #{u['media_url_https']}" unless u['media_url_https'].nil?
} unless extended_media.nil?
p "Lang: #{lang}" unless lang.nil?
p "============================="
}
