Answer 1

Thanks to the post here Nokogiri replace tag values, I was able to modify it a bit and figure it out.

doc = Nokogiri::HTML::DocumentFragment.parse(html)
doc.search("*").each do |node|
  dummy = node.add_previous_sibling(Nokogiri::XML::Node.new("dummy", doc))
  dummy.add_previous_sibling(Nokogiri::XML::Text.new(node.to_s.gsub(/(?<=[.!?])(?!\*)/, "#{$1}*"), doc))
  node.remove
  dummy.remove
end

puts doc.to_html.gsub("<", "<").gsub(">", ">")
