require 'rexml/formatters/pretty' module REXML module Formatters # The Transitive formatter writes an XML document that parses to an # identical document as the source document. This means that no extra # whitespace nodes are inserted, and whitespace within text nodes is # preserved. Within these constraints, the document is pretty-printed, # with whitespace inserted into the metadata to introduce formatting. # # Note that this is only useful if the original XML is not already # formatted. Since this formatter does not alter whitespace nodes, the # results of formatting already formatted XML will be odd. class Transitive < Default def initialize( indentation=2, ie_hack=false ) @indentation = indentation @level = 0 @ie_hack = ie_hack end protected def write_element( node, output ) output << "<#{node.expanded_name}" node.attributes.each_attribute do |attr| output << " " attr.write( output ) end unless node.attributes.empty? output << "\n" output << ' '*@level if node.children.empty? output << " " if @ie_hack output << "/" else output << ">" # If compact and all children are text, and if the formatted output # is less than the specified width, then try to print everything on # one line @level += @indentation node.children.each { |child| write( child, output ) } @level -= @indentation output << "</#{node.expanded_name}" output << "\n" output << ' '*@level end output << ">" end def write_text( node, output ) output << node.to_s() end end end end
