nokogiri_bang_finders

This gem says "Nokogiri, if you can't find XML I want, yell about it."

Specifically, it adds the following methods:

• at!
• at_xpath!
• at_css!

...to Nokogiri::XML::Node and Nokogiri::XML::NodeSet.

Each method just calls its non-bang namesake and, if the result is nil, raises Nokogiri::XML::NotFound.

This gem is so tiny, you could just copy and paste its code. But if it's convenient, use it. :smile:

Installation

$ gem install nokogiri_bang_finders

... or via Bundler.

Requiring

Be sure to require 'nokogiri_bang_finders' after you require 'nokogiri'. It expects Nokogiri::XML::Node and Nokogiri::XML::NodeSet to be defined so that it can add methods to them.

Usage

Use these methods just like you would use the normal Nokogiri versions, but expect an exception if the XML doesn't contain what you're looking for.
