libxml是C语言写的xml解析库，是我们开发可移植程序的首选，下面讲述将其移植到android的步骤
1.下载已经配置好的源代码包android_libxml2.rar
http://pan.baidu.com/s/1sjpusFj
该包里还有libxml2所依赖的字符转码库libiconv，也是配置好了的。我们所做的就是先编译
libiconv，然后再编译libxml2,当然一块编译也是可以的。
2.先把libiconv改名为jni，用命令行进入当前目录，执行ndk-build
3.在把libxml2改名为jni，用命令行进入当前目录，执行ndk-build
4.在obj/local/armeabi下就会生成我们需要的静态库了
下面献上libxml2和libiconv的mk文件：
