Are the Xerces parsers Year-2000-compliant?

Are the Xerces parsers Year-2000-compliant?

Yes, Xerces-J and Xerces-C are Year 2000 compliant. They do not currently use any dates at all (at least until the XML Schema date datatypes are fully supported). However, you may still have Y2K problems if the underlying OS or Java implementation has problems with dates past year 2000 (e.g. OS calls which accept or return year numbers).

Most (UNIX) systems store dates internally as signed 32-bit integers which contain the number of seconds since 1st January 1970, so the magic boundary to worry about is the year 2038 and not 2000. But modern operating systems shouldn't cause any trouble at all.

How do I determine the version of &XercesCName; I am using?

How do I determine the version of &XercesCName; I am using?

The version string for &XercesCName; is in one of the header files. Look inside the file `src/xercesc/util/XercesVersion.hpp` or, in the binary distribution, look in `include/xercesc/utils/XercesVersion.hpp`.

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 &XercesCWindowsDLL;.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 &XercesCUnixLib;&XercesCUnixSoName;.a (or &XercesCUnixLib;.so.&XercesCUnixSoName; on Solaris/Linux/IA64 HP-UX and &XercesCUnixLib;.sl.&XercesCUnixSoName; on PA-RISC HP-UX). The version number is indicated in the name of the library.

Does &XercesCName; support XPath?

Does &XercesCName; support XPath?

No. The &XercesCName; &XercesCVersion; only has partial XPath implementation for the purposes of handling Schema identity constraints. For full XPath support, you can refer Apache Xalan C++ or other Open Source Projects like Pathan.
