我正在尝试将 xml 文件 blog.xml 输出为 yaml,以放入 vision.app,这是一种用于在本地设计 shopify 电子商务网站的工具。
Shopify 的 yaml 如下所示:
- id: 2
handle: bigcheese-blog
title: Bigcheese blog
url: /blogs/bigcheese-blog
articles:
- id: 1
title: 'One thing you probably did not know yet...'

我天真地认为从一种序列化数据格式转换为另一种是相当简单的,我可以简单地这样做:
>> require 'hpricot'
=> true
