Accessing your Virtualbox Guest from your Host OS

As a developer you want to ping and access the webserver on your virtual machine. This is a very simple solution to enable the bridge to the guest VM.

Requirements

VirtualBox (latest version)
A guest operation system (e.g. Ubuntu)

	# Dealing with namespaces in Nokogiri.
	#
	# First thing you must do is abandon what you're used to with Builder,
	# namespaces aren't just attributes on an element, they uniquely identify
	# what sort of element you are building and, as such, you are better off
	# specifying them manually.
	#
	# The key here is accessing the Nokogiri::XML::Element being built with
	# b.parent, then you can set the namespace (distinguished by an element
	# with a prefix such as "soap12:Envelope") or add a default namespace

	// This needs to go in the "~/.config.sublime-text-3/Packages" folder on Linux.
