Yes, this is possible. The step-by-step instructions would be compiler
and platform-specific (both which you failed to mention, BTW). But 
generally, you need to download, build, and install the XQilla library 
in addition to Xerces-C++ and then link both to your application.

There is also the 'xpath' example in the examples/cxx/tree/ directory
of the XSD distribution which shows how to use XPath with C++/Tree.
It includes the README file which describes the example in detail
as well as the makefiles and project/solution files. So you may want 
to get this example working first and then base your own code on it.
