Validator features 2006-12-11 - By kris2006
Michael,
Thank you for your lightning response.
I was able to cast my jaxp Validator object as a PSVIProvider, in theory
giving me access to the getElementPSVI() methods to find the value of
validationAttempted, as you've suggested. However, getElementPSVI() returns
a null, I presume since it is only valid within the start/end of the
element, and I am simply using:
...
Schema schema = schemaFactory.newSchema(schemaSource);
Validator validator = schema.newValidator();
validator.validate(streamSource);
and so no longer have a context for getElementPSVI().
Any idea how do I could return a valid ElementPSVI?
Thanks again for your help...
Regards,
Kris
