更改boost属性树的数据类型

Question

Based on my previous post here, I take it that it is not possible to read an xml file directly into a property tree of char16_t .

https://stackoverflow.com/questions/28689003/using-boost-xml-parser-to-load-a-property-tree-with-char16-t

So I am looking at reading it as a regular char and then converting them to char16_t . I can handle the conversion between char and char16_t correctly, however I am not sure how to copy the data from one property tree to another.

I thought I can iterate over ptree but looks like I can only iterate on 1st level of children. I am not sure how to get the recursive call to duplicate a ptree with different data type.

Any tips?

如果有人在这篇文章中偶然发现试图以递归方式从一个ptree复制到另一个ptree，你可以在这里查看函数ptree_to_ptree（）： http ：//coliru.stacked-crooked.com/a/a7e0c2393ed9a98e
