Modifying text inside html nodes - nokogiri

Question

Let\'s say i have the following HTML:

Bullet 1.
Bullet 2.
Bullet 3.
Bullet 4.&         


        

Answer 1

What about this code?

doc.traverse do |x|
  if x.text?
    x.content = x.content.gsub(/(?<=[.!?])(?!\*)/, "#{$1}*")
  end
end

The traverse method does pretty much the same as search("*").each. Then you check that the node is a Nokogiri::XML::Text and, if so, change the content as you wished.
