NiXPS Library (v0.3.0) available for testing
NiXPS Library is a C/C++ shared library that contains all the functionality you have in the XPS Workbench application. I've been sending early versions to a few interested parties already (and got some very valuable feedback: thanks!).
To reach a broader audience, I've put a notice on my site that it's available for testing.
I'm taking a bit of a different approach than with the XPS Workbench app (that one can be downloaded, no questions asked), reason for this is the more technical nature of distributing a shared library and headers.
If your interested in a library that gives you access to an xps file (list documents and pages), read core properties, merge documents, add/delete pages and works cross-platform: then drop me line
