A small nokogiri xml reader DSL.
View xml_parser.rb
# 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:
# 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:
View sidebar.html.erb
<% @categories.each do |category| %>
<ul class="X">
<h5><%= link_to, category %></h5>
<% end %>
