I'm trying to output an xml file blog.xml as yaml, for dropping into vision.app, a tool for designing shopify e-commerce sites locally.
Shopify's yaml looks like this:
- id: 2
handle: bigcheese-blog
title: Bigcheese blog
url: /blogs/bigcheese-blog
articles:
- id: 1
title: 'One thing you probably did not know yet...'

I naively assumed converting from one serialised data format to another was fairly straightforward, and I could simply do this:
>> require 'hpricot'
=> true
>> b = Hpricot.XML(open('blogs.xml'))
>> puts b.to_yaml
But I'm getting this error.

How can I get the data output in the form outlined at the top of this question? I've tried importing the 'yaml' gem, thinking that I'm missing some of those methods, but that hasn't helped either:
