How to nest params using Nokogiri

Question

I want to create XML like this:

<categories>

 <category id=1>Sound</category>

 <category id=2 parentId=1>Speakers</category>

</categories>

I used:

   require 'nokogiri'

    @builder = Nokogiri::XML::Builder.new do |xml|

      xml.root {

        xml.categories{

           Category.all.each do |c|

             xml.category# here i should insert my needs



      end

    }

  }

end

I used an example from "docs about Tag Attribute Short Cuts" but it gave me

class

and

id

instead what I want.

How do I do it properly?

Answer 1

can you try below code, it will add the id attribute to the category tag.

require 'nokogiri'
  @builder = Nokogiri::XML::Builder.new do |xml|
  xml.root {
    xml.categories{
       Category.all.each do |c|
         xml.category(c.name, "id" => c.id)
  end
  }
}
end

Output should be like.

<categories>
 <category id=1>Sound</category>
 <category id=2>Speakers</category>
</categories
