Hannya
Hannya is a simple facade/data access layer that can take in either a hash (from a YAML or JSON file) or an XML object (from Nokogiri) and make them both look the same.
Mainly this is for XML. Why? Most of the time, if we are querying XML, we are looking for text values. This returns the value of a text node, if there is one at the location specified, and if not, returns another facade covering the nodeset that was found. You can use direct XPaths by passing them in brackets. The contents of brackets get passed directly into Nokogiri's #xpath method.
Support for direct data structures is experimental.
You can create an instance of Hannya::Mask with a text transformation rule that translates a snake case symbol to whatever is in the actual XML, and this will get run on the method name to convert it to an XPath.
Installation
Add this line to your application's Gemfile:
gem 'hannya'And then execute:
$ bundle
Or install it yourself as:
$ gem install hannya
Usage
require 'hannya'
xml = Nokogiri::XML(File.open 'myfile.xml')
