Libxml++

libxml++ is a C++ API for the popular libxml XML parser, written in C. libxml is famous for its high performance and compliance to standard specifications, but its C API is quite difficult even for common tasks.

libxml++ presents a simple C++-like API that can achieve common tasks with less code. Unlike some other C++ parsers, it does not try to avoid the advantages of standard C++ features such as namespaces, STL containers or runtime type identification, and it does not try to conform to standard API specifications meant for Java. Therefore libxml++ requires a fairly modern C++ compiler such as g++ 3.

But libxml++ was created mainly to fill the need for an API-stable C++ XML parser which could be used as a shared library dependency by C++ applications that are distributed widely in binary form. That means that installed applications will not break when new versions of libxml++ are installed on a user's computer. Gradual improvement of the libxml++ API is still possible via non-breaking API additions, and new independent versions of the API that can be installed in parallel with older versions. These are the general techniques and principles followed by the GNOME project, of which libxml++ is a part.
