Overview

Ox::Mapper’s intention is to simplify usage of Ox::Sax parsers All you need to do is to setup callbacks for elements and attributes in Ruby style

Example:

mapper = Ox::Mapper.new
mapper.on_element(:book) { |e| puts book.attributes.inspect }
mapper.on_element(:title) { |e| e.parent[:title] = e.text }

mapper.collect_attribute(:author => :name)
mapper.on_element(:author) { |e| e.parent[:author] = e[:name] }

# setup transformation for attribute "value" of "price" element
mapper.on_attribute(:price => :value) { |v| Float(v) }
mapper.on_element(:price) { |e| e.parent[:price] = e[:value] }

mapper.parse(StringIO.new <<-XML) # => {:title => "Serenity", :author => "John Dow", :price => 1123.0}
  <xml>
    <book>
      <title>Serenity</title>
      <author name="John Dow" />
      <price value="1123" />
    </book>
  </xml>
