Ruby解析XML文件

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 --"
