Nokogiri shares all attributes

Question

I have this html markup:

<div class="item"><a href="www"></a></div>

and I would like to get the following:

<div><a></a></div>

How can I do this with Nokogiri?

Answer 1

require 'nokogiri'
doc = Nokogiri::HTML('<div class="item"><a href="www"></a></div>')

• You can remove all attributes with xpath:

  doc.xpath('//@*').remove
  

• Or, if you ever need to do something more complex, it is sometimes easier to cross all the elements with:

  doc.traverse do |node| 
    node.keys.each do |attribute|
      node.delete attribute
    end
  end
  

Answer 2

This works for everyone except the xml namespace attributes (xmlns =). You can also easily remove them using doc.remove_namespaces! (turn on the exclamation mark, otherwise it will not delete them)
