I have a problem with Nokogiri::XML::Builder. I am generating XML wth this code:

builder = Nokogiri::XML::Builder.new do 
    request {
        data '1'
    }
end

And the result is:

<?xml version="1.0" encoding="UTF-8"?><request><data>1</data></request>

How can I remove:

<?xml version="1.0" encoding="UTF-8"?>

from my XML?

Maybe take just the root node of the current Document object being built – .doc – instead of the whole document?

builder.doc.root.to_s

Should be `builder.doc.root.to_xml` (or `to_s`). – Phrogz Jan 18 '12 at 01:44

A quick and dirty answer is to tell Nokogiri to reparse the resulting output, then look at the root:

require 'nokogiri'

builder = Nokogiri::XML::Builder.new do 
  request {
    data '1'
  }
end

puts Nokogiri::XML(builder.to_xml).root.to_xml

Which outputs:

<request>
  <data>1</data>
</request>
