Dave,
Thanks for responding.
We need to validate XML files against the same XSD files in both our
Java client code and C++ server code. Hence the need to use both
Xerces-J and Xerces-C++.
Since we are using both Xerces-J and Xerces-C++, I wanted to make sure
that the validation is consistent across Java and C++ e.g. if the
validation fails for some reason in the Java client code, I am expecting
the validation to fail for the same reason in the C++ server code as
well.
I doubt you will be able to do that. My experience is that Xerces-J and
Xerces-C are inconsistent in their handling of the schema recommendation,
although mostly this is in the edge cases. There has been a fair amount of
work done to get them aligned, but XML Schema is a very complex
recommendation, so it's tough. In addition, there is a fair amount of
working tracking the errata that are issued, and I don't know how much
effort is being exerted to do that.
In general, trust Xerces-J rather than Xerces-C. However, we would love to
hear about the cases where the results are different. We will do our best
to get them aligned.
