##
## The sample for Ruby style visitor.
## You can use "each" method as the iterator to visit all nodes,
## and can also use the other Enumerable module methods.

require 'xmltreebuilder'
require 'xmltreevisitor'
require 'xmlencoding-ja'
include XMLEncoding_ja

p = XML::SimpleTreeBuilder.new(1)
tree = p.parse($<)
tree.documentElement.normalize

tree.each_with_index do |node, index|
  print format("%03d: ", index)
  case node.nodeType
  when XML::SimpleTree::Node::ELEMENT
    print "<#{node.nodeName}>\n"
  when XML::SimpleTree::Node::DOCUMENT
    print "#DOCUMENT\n"
  else
    print "#{Uconv.u8toeuc(node.to_s).inspect}\n"
  end
