lua 解析 xml 文件，含内嵌

-- 导入依赖文件require('LuaXml')local socket = require "socket"-- 加载XML文件local xfile = xml.load("student.xml")-- 添加子节点local xNewFile = xml.new("student")local start_time = socket.gettime()for i=1, 1000 do-- 查找子节点local id = xfile:find("id")local name = xfile:find("name")local cla = xfile:find("cla")local school = xfile:find("school")local college = xfile:find("college")local email = xfile:find("email")local phone = xfile:find("phone")end-- 设置子节点键值xNewFile:append("id")[1] = 10xNewFile:append("name")[1] = "LUA"xNewFile:append("cla")[1] = "wang"xNewFile:append("school")[1] = "zh"xNewFile:append("college")[1] = "xin"xNewFile:append("email")[1] = "[e-mail]"phone = xNewFile:append("phone")phone:append("number")[1] = "158"print( xNewFile);-- 保存文件xNewFile:save"student_new.xml";local end_time = socket.gettime()print(end_time-start_time)

student.xml文件内容如下：

<student>      <id>10</id>      <name>LUA</name>    <cla>wang</cla>    <school>zh</school>     <college>xin</college>    <email>[e-mail]</email>    <phone num="1">        <field number="158"></student> 

得到的student_new.xml文件：

<?xml version="1.0"?><!-- file "student_new.xml", generated by LuaXML --><student>  <id>10</id>  <name>LUA</name>  <cla>wang1</cla>  <school>zh</school>  <college>xin</college>  <email>[e-mail]</email>  <phone>    <number>158</number>  </phone></student>
