接口说明

local xml = require("luaxml")
--编码
--value: 输入的lua table
--header: xml的自定义头，不传使用默认
--res：输出xml字符串
--err：错误信息
local res, err = xml.encode(value)
local res, err = xml.encode(value, 'xml version="1.0" encoding="gbk"')

--解码
--value: 输入的xml字符串
--res：输出lua
local res = xml.decode(value)

--保存到文件
--xmlfile: 保存的xml文件名
--value: 输入的lua
--header: xml的自定义头，不传使用默认
--res：成功或者失败
local ok = xml.save("./bb.xml", xxlua, 'xml version="1.0" encoding="gbk"')

--从文件读取
--xmlfile: 读取的xml文件名
--res：输出xml字符串
--err：错误信息
local flua, ferr = xml.open("./bb.xml")
