Can the below output be pretty-print ?

require 'nokogiri'

doc =  Nokogiri::HTML::DocumentFragment.parse(<<-html)
<p>First</p>
<p>Second</p>
<p>Third</p>
html

nodeset = doc.css("p")
new_node = Nokogiri::XML::Node.new('span',doc)
new_node << nodeset[1..-1]
nodeset.first.after(new_node)
puts doc.to_html
# >> <p>First</p><span><p>Second</p>
# >> <p>Third</p></span>
# >>

expected :

# >> <p>First</p>
# >>    <span>
# >>        <p>Second</p>
# >>        <p>Third</p>
# >     </span>

Thanks - for the reply.

You can see my comments below in the answer of @phrogz
to the first
hit(http://stackoverflow.com/questions/1898829/how-do-...)

But it not helped me.

require 'nokogiri'

doc =  Nokogiri.HTML(<<-html,&:noblanks)
<p>First</p>
<p>Second</p>
<p>Third</p>
html


nodeset = doc.css("p")
new_node = Nokogiri::XML::Node.new('span',doc)
new_node << nodeset[1..-1]
nodeset.first.after(new_node)
puts doc.to_html( indent:3, indent_text:"." )
