boost::property_tree::ptreeprovides the member functionsbegin()andend(). However,boost::property_tree::ptreeonly lets you iterate over the branches in one level.Example 25.2iterates over the subdirectories of C:\Windows. You can’t get an iterator to iterate over all branches in all levels...

使用这个 lib 只需要 include 对应的 boost/property_map/ptree.hpp,然后载入 xxx_parser.hpp 以获得对对应格式的支持。一般可以用 read_xxx(filename, ptree) 将文件读入 boost::property_tree::ptree 中,之后我们可以用 get 模板方法(可带缺省值)获得某个 node 里面的值(并转换类型),对应使用的是到该 no...
