Description of the illustration ''xmlisvalid.gif''


XMLISVALID checks whether the input XMLType_instance conforms to the relevant XML schema. It does not change the validation status recorded for XMLType_instance.

If the input XML document is determined to be valid, then XMLISVALID returns 1; otherwise, it returns 0. If you provide XMLSchema_URL as an argument, then that is used to check conformance. Otherwise, the XML schema specified by the XML document is used to check conformance.

  • XMLType_instance is the XMLType instance to be validated.

  • XMLSchema_URL is the URL of the XML schema against which to check conformance.

  • element is the element of the specified schema against which to check conformance. Use this if you have an XML schema that defines more than one top level element, and you want to check conformance against a specific one of those elements.
