#prettify(xml_doc) ⇒ Object
Returns a nicely indented XML document. Note that the XSL file was taken from the (apparently defunct) nokogiri-pretty project: github.com/tobym/nokogiri-pretty/blob/master/lib/indent.xsl The only modification made was to declare UTF-8 to be the encoding, instead of ISO-8859-1.
