Answer 1

require 'nokogiri'

html = '
bla bla
'
doc = Nokogiri::HTML(html)
doc.xpath('//@style').remove
puts doc.css('.post')
#=> 
bla bla

Edited to show that you can just call NodeSet#remove instead of having to use .each(&:remove).

Note that if you have a DocumentFragment instead of a Document, Nokogiri has a longstanding bug where searching from a fragment does not work as you would expect. The workaround is to use:

doc.xpath('@style|.//@style').remove
