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.

Answer 2

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("&lt;", "<").gsub("&gt;", ">")
