将XML集合(Pivotal Tracker故事)转换为Ruby散列/对象

require 'nokogiri'

xml_string = '<stories>
 <story>
    <id>1</id>
    <name>Story 1</name>
   <description>This is the first story</description>
  </story>
 <story>
    <id>2</id>
    <name>Story 2</name>
   <description>This is the second story</description>
  </story>
</stories>'

# 解析XML字符串
doc = Nokogiri::XML(xml_string)

# 获取所有story节点
stories = doc.xpath('//story')

# 创建一个空数组来存储Ruby散列
ruby_stories = []

# 遍历所有story节点
stories.each do |story|
  # 创建一个新的Ruby散列来存储当前story的信息
  ruby_story = {}

  # 获取id、name和description节点的值
  ruby_story[:id] = story.xpath('id').text.to_i
  ruby_story[:name] = story.xpath('name').text
  ruby_story[:description] = story.xpath('description').text

  # 将当前story散列添加到ruby_stories数组中
  ruby_stories<< ruby_story
end

# 输出结果
puts ruby_stories.inspect
