libxml++2.6-2v5 2.40.1-1 (amd64 binary) in ubuntu zesty

 Libxml++ is a C++ wrapper for the libxml2 XML parser library (otherwise
 known as the GNOME XML library). It has SAX and DOM-like APIs, but does not
 attempt to conform exactly to the DOM specification because they are not
 aimed at C++. Its API is much simpler than the underlying libxml C API.
