Ok, I got the validator.pl sample (from 
http://svn.apache.org/repos/asf/xml/xerces-p/trunk/samples/validator.pl) 
but it requires that the schema be specified in the xml document being validated;
I need to be able to specify a schema in my code.

I've been working from the xerces-c examples at
http://xml.apache.org/xerces-c/schema.html#associate but I'm having trouble converting these to perl.

I tried using SAX first (as validator.pl does) but I couldn't figure out how to call setProperty to associate my external (no namespace) schema with the parser.
I tried this:

#!/usr/bin/perl -w

use XML::Xerces;
use strict;

my $parser = XML::Xerces::XMLReaderFactory::createXMLReader();
my $schema = "ownership3Document.xsd.xml";


$parser->setFeature("$XML::Xerces::XMLUni::fgSAX2CoreNameSpaces", 1);
$parser->setFeature("$XML::Xerces::XMLUni::fgXercesSchema", 1);
$parser->setFeature("$XML::Xerces::XMLUni::fgSAX2CoreValidation", 1);
$parser->setFeature("$XML::Xerces::XMLUni::fgXercesDynamic", 0);
$parser->setFeature("$XML::Xerces::XMLUni::fgXercesSchema", 1);
$parser->setProperty(
     "XMLUni::fgXercesSchemaExternalNoNameSpaceSchemaLocation",
                     $schema);

$parser->parse(XML::Xerces::LocalFileInputSource->new("doc3.xml"));


but that gives me the error

Type error in argument 3 of SAX2XMLReader_setProperty. Expected _p_void at
xerces_test.pl line 15.

I've tried many variations on this theme, but nothing seems to work.  That's when I decided to try the DOM parser and was able to set the schema with no problem (using $parser->setExternalNoNamespaceSchemaLocation).  It's my DOM parser which dies after it hits the first error.

So I need to either figure out how to set my schema in the SAX version, or get it to not die on the first error in the DOM version.

Any ideas?
