//xml 由xml文档头(文档头 <? ?>包含) 文档的主体

//1.添加libxml2.dylib库(系统库), 在bulid Phases中添加二进制库 (在link Binary With libraries 选项)
//2.在bulid Setting中 添加头文件路径, search paths 下的 header search paths -->/usr/include/libxml2
//3.添加GDataXMLNode库(第三方库) arc  mrc 混合编程 (在bulid Phases下 complie sources GDataXMLNode.m 文件)  -fno-objc-arc
