项目的配置文件是XML，项目中用了脚本语言LUA 5.3，找了几个lua解析xml的库，测试都不怎么样，有些是因为LUA的版本比较旧，用得话还得转(虽然工作量不大)，最后找到了luaxml ，发现节点检索超方便。

　　

xml = require('LuaXml')-- load XML data from file "test.xml" into local table xfilelocal xfile = xml.load("test.xml")print(type(xfile))-- search for substatement having the tag "scene"local xscene = xfile:find("id","id","5")-- if this substatement is foundif xscene ~= nil then  --  print it to screen  print(xscene)  --  print  tag, attribute id and first substatement  print(xscene.id,xscene.buildLevel)end--xfile:save"t.xml"print("---\nREADY.")for i,node in pairs(xfile:find("root")) do    print("tag is ",node.tag)    if node.tag~=nil and node[node.tag]=="id" then    print(node.id,node.buildLevel,node.upGrade)    endendlocal f2 = xml.load("test2.xml")local section = f2:find("section","id","0")local difficulty=section:find("difficulty","id","1")local level=difficulty:find("level","id","0")print(level.point)

function xml.find(var, tag, attributeKey,attributeValue)

recursively parses a Lua table for a substatement fitting to the provided tag and attribute

• • param var, the table to be searched in.
  • param tag (optional) the xml tag to be found.
  • param attributeKey (optional) the exact attribute to be found.
  • param attributeValue (optional) the attribute value to be found.
  • Returns the first (sub-)table which matches the search condition or nil.

 有个坑，

xml = require('LuaXml')这里一定要设置为全局的，加个local会出事的
