Set Error Handler() as in the example in this SO question stackoverflow.com/questions/4864681/…?(For SAX parsing, on the other hand, you set a property on the parser generated by the factory).Now that the program is ready to validate with an XML Schema definition, it is necessary only to ensure that the XML document is associated with (at least) one.At the end of this section, you will also learn how to use an XML Schema definition to validate a document that contains elements from multiple namespaces.To be notified of validation errors in an XML document, the following must be true: It is helpful to start by defining the constants you will use when configuring the factory.
