/*DOM是系统不支持的

可以使用谷歌提供的GDateXMLNode

步骤：

1.引用类库libxml2

2.build setting -> Header search Paths 下

添加 ：/usr/include/libxml2

Other Linker Flags 下

添加： -lxml2

3.GDataXMLNode 是在MRC下写的， 要想在ARC环境下使用需要做一些操作

build Prases下  搜索 GData 添加 -fno-objc-arc

创建表格----初始化数组—导入AFN框架—引入头文件—-创建AFN方法——开始用AFN请求—infoplist(打开网络)——创建BaseModel—-创建Basetableviewcell—注册表格(viewdidload[在表格下面])
