gkellogg / rdfa_xmlliteral_serialization.rb
Created October 24, 2010 06:42
Code use to place XMLLiteral in canonical form and preserve @Profile, @Prefix, @vocab and @lang mappings.
# Add already mapped namespaces and language
@contents = contents.map do |c|
c = Nokogiri::XML.parse(c.copy(true).to_s) if c.is_a?(LibXML::XML::Node)
if c.is_a?(Nokogiri::XML::Element)
c = Nokogiri::XML.parse(c.dup.to_xml(:save_with => Nokogiri::XML::Node::SaveOptions::NO_EMPTY_TAGS)).root
# Gather namespaces from self and decendant nodes
#
# prefix mappings
# Look for @xmlns and @prefix mappings. Add any other mappings from options[:prefixes]
# that aren't already defined on this node
