This is a feature complete XML library containing a validating parser as well as a modern C++ API for the data structures. It also supports serializing custom data structures. The core of this library is a validating XML parser with DTD processing and all. On top of this are implemented an API for manipulating XML data in a DOM like fashion and a serialization API. As a bonus there’s also an XPath implementation, albeit this is limited to XPath 1.0. This XML library was extracted from libzeep since having a separate and simple XML library is more convenient. The API is unfortunately no longer compatible since the goal was to be more standards compliant. E.g., zeem::element should now be a complete Sequence Container.
