##安装LuaXml 下载 然后修改Makefile

主要修改如下几个地方：
INCDIR = -I/usr/local/openresty/luajit/include/luajit-2.1LIBDIR = -L. -L/usr/local/openresty/luajit/libLIBS = $(LIBDIR) $(LIB) -lluajit-5.1 -ldlLIBS = $(LIBDIR) -L/usr/local/lib $(LIB) -lluajit-5.1LIBS = $(LIBDIR) $(LIB) -llua51 -mconsole -s
拷贝到openresty/openresty:1.11.2.1-trusty镜像实例中，然后再此基础上编译
make clean && make
然后拷贝LuaXML_lib.so以及LuaXml.lua到/usr/local/openresty/lualib/
##使用luaxml
require "LuaXml" xml = require "xml" local resp = xml.eval(xmlStr) local oktag = resp:find("ok") local ok = oktag[1] ngx.log(ngx.INFO,"ok tag:"..ok) - 关于xml 如果不require "xml"，而是直接用xml的话，则第二次请求会报错
attempt to index global 'xml' (a nil value)
- 关于eval 返回的是lua table，通过find出来，也是一个table，取出相应的值接口，如果是单值，取数组第一个，比如xmlStr是
false
