Validation with 2.8.0 not working as documented.

[David Siefert <si...@yahoo.com>]

Hi,
I am attempting to validate an XML document with an XML schema using the xerces-c 2.8.0 API.  I do roughly the following:
<code>
  XercesDOMParser parser = new XercesDOMParser();
  parser->setDoNamespaces(true);
  parser->setDoSchema(true);
  parser->setValidationScheme(XercesDOMParser::Val_Always);
  parser->setExternalSchemaLocation(XMLString::transcode("urn:thenamespace path\\to\\the\\schema.xsd"));
  const char* xmlFile = "path\\to\\xml\\document\\with\\invalid\\element.xml";
  parser->parse(xmlFile);
</code>
I am able to query through the document nodes without any exception being thrown.  But the document contains an element not defined by the schema.  Am I forgetting a step somewhere?
Thanks,
David

This is a memory leak.  You need to free the pointer return by 
XMLString::transcode().

You need to install an ErrorHandler to detect errors.  If you want to 
stop parsing, you can throw an exception from your ErrorHandler.
