Internal State Validation Exception if any object resurrected was a Validatable which did not pass validation.Hi Experts, I was looking for validation of XML string against XSD.The validator checks for well formedness first, meaning that your XML file must be parsable using a DOM/SAX parser, and only then does it validate your XML against the XML Schema.
The validator will report fatal errors, non-fatal errors and warnings.Recently in my project, I had a requirement to validate XML file against XSD schema file and list all validation errors.
