I am not aware of a (simple) library parsing this outside of an R context
(and within the R context, I'd always start with Rserve from RForge.net).

But you could look into general serialization / translation libraries such as
Google Protocol Buffers (see https://developers.google.com/protocol-buffers/)
which can also translate into C++, Java, Python plus a host of
user-contributed bindings. 

For R, you will find a package RProtoBuf on CRAN.  There are other, related
libraries but I have worked only with Protocol Buffers.
