The thing about Xerces that's such a lifesaver is how it can
cache the schema so you can validate hundreds or thousands
of XML documents in no time at all. I don't know if other
validation toolkits and libraries can do that nowdays but
it sure was the answer to my prayers when I researched all of
this back when. Here are my settings:
my $parser = XML::Xerces::XMLReaderFactory::createXMLReader();
$parser->setErrorHandler(new ErrorHandlers);
$parser->setFeature("$XML::Xerces::XMLUni::fgXercesSchemaFullChecking", 1);
$parser->setFeature("$XML::Xerces::XMLUni::fgXercesContinueAfterFatalError", 1);
$parser->setFeature("$XML::Xerces::XMLUni::fgXercesValidationErrorAsFatal", 0);
$parser->setFeature("$XML::Xerces::XMLUni::fgSAX2CoreValidation", 1);
$parser->setFeature("$XML::Xerces::XMLUni::fgXercesDynamic", 1);
$parser->setFeature("$XML::Xerces::XMLUni::fgXercesCacheGrammarFromParse", 1);
$parser->setFeature("$XML::Xerces::XMLUni::fgXercesUseCachedGrammarInParse", 1);
There have been many instances where Xerces has disagreed with
other validators and it's always turned out Xerces was right.
XML Spy, for example, is wrong A LOT. In my community Xerces has
always been viewed as the cadillac of validators.

I got the Xerces stuff working. Just followed the directions.

As with so many other chores, the 'doing it' was straight forward. The
'figuring out which way to do it is better/best' was a pain.

The Xerces-p distribution comes with some examples including
'validate.pl' and is exactly what I was trying to do. It reports
errors by line and column and schema error. Perfect.
