# Nokogireader

DSL for parsing xml using Nokogiri::XML::Reader

## Installation

Add this line to your application's Gemfile:

```ruby

gem 'nokogireader'

```

## Example

```rb

class Rss2 < Nokogireader::Reader

  element :rss, attr: [:version] do

    element :channel do

      elements :item do

        element :title

        element :link

      end

    end

  end

end

data = Rss2.new.read(File.open('rss2.xml'))

puts "Version: #{data.rss.attributes[:version]}"

puts "Items: #{data.rss.channel.item.size}"

data.rss.channel.item.each do |item|

  puts " > #{item.title.text}"

end

```

You can use ``after`` callback and ``dont_store_data`` to reduce memory usage.

```rb

class Rss2 < Nokogireader::Reader

  element :rss, attr: [:version] do

    element :channel do

      elements :item do

        dont_store_data

        element :title

        element :link

        after do |reader, item|

          puts "Title: #{item.title.text}"

        end

      end

    end

  end

end

data = Rss2.new.read(File.open('rss2.xml'))

puts "Items: #{data.rss.channel.item.size}" # => 0. If specified "dont_store_data", data isn't stored.

```
