## Visitor sample
## 1998 by yoshidam
##
## 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 'xml/dom/builder'
require 'xml/dom/visitor'
require 'xml/encoding-ja'
include XML::Encoding_ja
p = XML::SimpleTreeBuilder.new(1)
tree = p.parse($<.read)
tree.documentElement.normalize
tree.each_with_index do |node, index|
print format("%03d: ", index)
case node.nodeType
when XML::SimpleTree::Node::ELEMENT_NODE
print "<#{node.nodeName}>\n"
when XML::SimpleTree::Node::DOCUMENT_NODE
print "#DOCUMENT\n"
else
print "#{Uconv.u8toeuc(node.to_s).inspect}\n"
end
end
