The version string for Xerces-C++ is in one of the header files. Look
inside the file src/xercesc/util/XercesDefs.hpp
or, in the binary distribution, look in include/xercesc/utils/XercesDefs.hpp
. Search for the static variable gXercesFullVersionStr
and look at its definition. (It is usually a string like "1_4_0" or
something similar). This is the version of Xerces-C++ you are using.
If you don't have the header files, you have to find the version
information from the shared library name. On Windows right click on
the DLL name xerces-c_1_7_0.dll in the bin directory and look up
properties. The version information may be found on the Version tab.
On AIX, just look for the library name libxerces-c1_7_0.a (or
libxerces-c1_7_0.so on Solaris/Linux and libxerces-c1_7_0.sl on HP-UX). The
version number is coded in the name of the library.
