Sax validating

15 Feb

If you create an object implementing this interface, then register the object with your Parser, the parser will call the method in your object to resolve all external entities.

Interface used by the parser to present error and warning messages to the application.

We also saw how to validate the document using DTD while using the SAXBuilder. The example below specifies two methods to specify an XSD externally.

In this tutorial we look at how to use the SAXBuilder that validates against an XSD.

The example below shows how to use an internally defined XSD.

The example after that shows how to define an XSD externally.

If an application attempts to query or set a feature flag that the XML reader does not recognize (can't get or set the value for), the XML reader throws a SAXNot Recognized Exception.

(That might indicate an application provided the wrong URI.) If the application attempts to set a feature state or property value that the XML reader cannot support at that time, or attempts to modify a feature or property when it is read-only, the XML reader throws a SAXNot Supported Exception.

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.If the XSD is publicly available using HTTP and referenced through a "schema Location" or "no Namespace Schema Location", then the validator will pick it up and it doesn't need to be specified/uploaded.Applications normally only need to implement those interfaces whose events they are interested in; they can implement the interfaces in a single object or in multiple objects.Handler implementations should inherit from the base classes provided in the module Basic interface for resolving entities.
