Nokogiri to_xml without carriage returns

Question

I\'m currently using the Nokogiri::XML::Builder class to construct an XML document, then calling .to_xml on it. The resulting string always contains a bunch of spaces, line

Answer 1

b.to_xml returns a string. You just need to replace the first instance of \n in the string.

require 'nokogiri'

b = Nokogiri::XML::Builder.new do |xml|
  xml.root do
    xml.text("Value")
  end
end

b.to_xml.sub("\n",'')

Probably easier than trying to overload the method.
