The Boost PropertyTree library provides a data structure that stores an arbitrarily deeply nested tree of values, indexed at each level by some key. It serializes and emulates XML, JSON and INI file structures.

Note: Boost.PropertyTree is not a generic XML parser. It is not intended to be used as a fast-and-dirty way to load arbitrary XML files into memory. It's XML serialization capabilities are for serialization. It is intended to read the XML that it has written.

Please stop using Boost.PropertyTree as a generic XML parser.
