在做聚合SDK开发时，Android方向会遇到从Java编译到APK打包的一系列问题，其中有一项就是需要合并多个工程中AndroidManifest.xml以及strings.xml、styles.xml中的信息，这样才能使用aapt工具生成正确的R.java文件。
但由于AndroidManifest.xml中，字段名中包含 "android:" 带冒号的特殊字符串，所以还无法使用序列化解析XML的方式处理。
目前我通过解码的方式读取出XML中的所有字段信息，保存在结构体的数组对象中，这样既方便记录字段信息，又方便做去重处理。直到全部XML处理完毕，再将结构体生成成一个新的XML文件导出。
1. AndroidManifest.xml合并代码
参数:
-m : 主要XML文件的路径，相同属性以主XML为准。
