FTFY

require 'rubygems'
require 'nokogiri'

doc = Nokogiri::XML(DATA.read) { |cfg| cfg.noblanks }

Nokogiri::XML::Builder.new do |xml|
   xml.doc     = doc
   xml.parent  = doc.at('dict')

   xml.key('gutter')
   xml.string('#282828')
end

puts doc.to_xml

__END__
<dict>
   <key>background</key>
   <string>#FFFFFF</string>
   <key>caret</key>
   <string>#000000</string>
   <key>foreground</key>
   <string>#000000</string>
   <key>invisibles</key>
   <string>#BFBFBF</string>
   <key>lineHighlight</key>
   <string>#00000012</string>
   <key>selection</key>
   <string>#BAD6FD</string>
</dict>


Doesn't use REXML, but does output the formatting you want.  Hope that  
helps!
