How is the request XML parsed

Hi all

When one sends for example a POST request with an XML body Rails parses this into a hash with a corresponding structure. How is this conversion done and where? Which XML library is used? Any pointers on where in the Rails source this is done would be helpful.

Kindest regards

See http://github.com/rails/rails/tree/v2.2.2/actionpack%2Flib%2Faction_controller%2Frequest.rb#L490

You can override what happens with

ActionController::Base.param_parsers[Mime::Type.lookup ('some_mime_type')] = Proc.new do |data|   #turn data into a hash of attributes end
