Ruby是一款对开发版本依赖度很高的语言，而且目前不支持中文（如果要使用中文字符，可使用UTF-8）
以下程序在 Ruby 1.8.6 下编译通过, IDE环境为 RubyMine [比NetBean好用]
# 解析XML文件
require "rexml/document"
include REXML
puts "-- BEGIN --"
doc = Document.new(File.open("TestXML.xml"))
#doc.elements.each('BoardComposant') do |elem|
# cr_ele = elem.get_elements('ComponantRectangle')
# puts cr_ele
#end
doc.elements.each("BoardComposant/ComponantRectangle"){ |elem|
if "second" == elem.attributes["name"] then
puts " => 2th"
puts elem.elements[2].elements["Height"].text
elem.elements.each{ |e|
puts e.elements["Height"].text
}
end
}
#----------------------------------------------
puts "-----------------------------------------"
#----------------------------------------------
input = File.new("book.xml")
doc = Document.new(input)
root = doc.root
puts root.attributes["shelf"] # Recent Acquisitions
doc.elements.each("library/section") { |e| puts e.attributes["name"] }
# Output:
# Ruby
# Space
doc.elements.each("*/section/book") { |e| puts e.attributes["isbn"] }
# Output:
# 0672328844
# 0321445619
# 0684835509
# 074325631X
sec2 = root.elements[2]
author = sec2.elements[1].elements["author"].text # Robert Zubrin
puts author
puts "-- End --"
