Using Nokogiri HTML Builder to create fragment with multiple root nodes

Well I have a simple problem with Nokogiri. I want to make Nokogiri::HTML::Builder to make an HTML fragment of the following form:

<div>
#Some stuff in here
</div>
<div>
#Some other stuff in here
</div>

When trying to do:

@builder = Nokogiri::HTML::Builder.new(:encoding => 'UTF-8') do |doc|
    doc.div {
      doc.p "fir开发者_运维百科st test"
    }
    doc.div {
      doc.p "second test"
    }
  end
@builder.to_html

I get an error: Document has already a root node, which I partly understand. I know I am not wrapping the whole thing into tags (which Nokogiri expects as Nokogiri::HTML::Builder inherits from Nokogiri::XML::Builder and an XML document must have a root node). But I am not building an XML document.

Am I missing something? Any kind of help is much appreciated.

As you noted, Builder will not allow you to build an HTML document with multiple root nodes. You'll need to use DocumentFragment

@doc = Nokogiri::HTML::DocumentFragment.parse ""

Nokogiri::HTML::Builder.with(@doc) do |doc|
    doc.div {
      doc.p "first test"
    }
    doc.div {
      doc.p "second test"
    }
end

puts @doc.to_html

Here is what I did for replacing images src attributes:

  doc = Nokogiri::HTML(html)
   doc.xpath("//img").each do |img|
     img.attributes["src"].value = Absolute_asset_path(img.attributes["src"].value)
  end
  doc.to_html
