xml测试数据

<project name="Protocol"><message id="0x42001003" name="S_CROSS_ARENA_UI" description="跨服争霸场角色信息"><field type="S_CROSS_ARENA_ROLE_INFO[]" name="roleList" description="角色列表"/><field type="S_CROSS_ROLE_TOP_THREE_INFO[]" name="topThreeRoles" description="前三名"/><field type="int" name="fightCap" description="战斗力"/><field type="int" name="rankNo" description="排名"/><field type="int" name="leftAttackCount" description="剩余战斗攻击次数"/><field type="int" name="leftFreeResetCount" description="剩余免费重置次数"/><field type="long" name="resetExpend" description="增加战斗次数消耗钻石数"/><field type="long" name="addAttackExpend" description="增加战斗次数消耗钻石数"/><field type="S_CROSS_ROLE_TOP_THREE" name="test" description="消耗"/><field type="int" name="score" description="积分"/><field type="boolean[]" name="gradeRewards" description="三个档次的奖励是否可领取"/></message></project>

生成lua

function read_S_CROSS_ARENA_UI(self)  --跨服争霸场角色信息local data = {roleList = { [1]={ read_S_CROSS_ARENA_ROLE_INFO }, },topThreeRoles = { [1]={ read_S_CROSS_ROLE_TOP_THREE_INFO }, },fightCap = 10,rankNo = 10,leftAttackCount = 10,leftFreeResetCount = 10,resetExpend = 100,addAttackExpend = 100,test = {  read_S_CROSS_ROLE_TOP_THREE },score = 10,gradeRewards = { [1]=true, },}end

用法，用里面的标示，找到其他的协议把里面的内容复制过来.

也可以用函数返回方式。生成代码这样：

function read_S_CROSS_ARENA_UI()  --跨服争霸场角色信息local data = {roleList = { [1]= read_S_CROSS_ARENA_ROLE_INFO(), },topThreeRoles = { [1]= read_S_CROSS_ROLE_TOP_THREE_INFO(), },fightCap = 10,rankNo = 10,leftAttackCount = 10,leftFreeResetCount = 10,resetExpend = 100,addAttackExpend = 100,test = read_S_CROSS_ROLE_TOP_THREE(),score = 10,gradeRewards = { [1]=true, },}return dataend
