# A small DSL for helping parsing documents using Nokogiri::XML::Reader. The
# XML Reader is a good way to move a cursor through a (large) XML document fast,
# but is not as cumbersome as writing a full SAX document handler. Read about
# it here: http://nokogiri.org/Nokogiri/XML/Reader.html
# 
# Just pass the reader in this parser and specificy the nodes that you are interested
# in in a block. You can just parse every node or only look inside certain nodes.
# 
# A small example:

Why?

There is a long standing issue in Ruby where the net/http library by default does not check the validity of an SSL certificate during a TLS handshake. Rather than deal with the underlying problem (a missing certificate authority, a self-signed certificate, etc.) one tends to see bad hacks everywhere. This can lead to problems down the road.

From what I can see the OpenSSL library that Rails Installer delivers has no certificate authorities defined. So, let's go fetch some from the curl website. And since this is for ruby, why don't we download and install the file with a ruby script?

Installation

The Ruby Way! (Fun)

class ApplicationController < ActionController::Base

  ...
  #Problem:
  #In rails 3.0.1+ it is no longer possible to do this anymore;
  #  rescue_from ActionController::RoutingError, :with => :render_not_found
  #
  #The ActionController::RoutingError thrown is not caught by rescue_from.
  #The alternative is to to set a catch-all route to catch all unmatched routes and send them to a method which renders an error
  #As in http://techoctave.com/c7/posts/36-rails-3-0-rescue-from-routing-error-solution
