As an example, the element elements are allowed (as in a lengthy novel with hundreds of pages).A DTD or an XML Schema plus a validating parser make a document usable across applications.
Note that tutorial examples given in this section were taken in 2002 using JDK 1.4 and Xerces-J 2.3.
Add Attribute( " Language", " Attribute( " Source", Schema Url);, using the JAXP parser.
For an XML document to be based on an XML schema, the XML document is required to be validated with the schema.
Because SAX is event driven, you'll want to be notified of, and react to, any errors that occur during validation. XMLReader Factory; public class Validate XML class My Error Handler implements Error Handler as it brings things to a crashing halt when any problems arise.
You can do this by using the SAX After making the changes per Listing 1, the parser will perform validation on documents, but you might not hear about any problems it encounters because this code doesn't provide a means to report errors. Instead of gracefully returning an error code to the parent application, I print the error to the screen and bail out of the code.
Validating a document's constraints, and providing this meaning to one or more XML documents, can be achieved easily by using SAX, the Simple API for XML (see Related topics).
In XML parsers, validation is usually turned off by default because many XML authors are not writing constraints; leaving it off helps to avoid lengthy processing in production environments. SAXParse Exception: cvc-type.3.1.1: Element 'body' is a simple type, so it cannot have attributes, excepting those whose namespace name is identical to ' and whose [local name] is one of 'type', 'nil', 'schema Location' or 'no Namespace Schema Location'. Error Handler; class Xsd Schema Sax Validator With Error Handler java Xsd Schema Sax Validator With Error Handler first_first_html_extra_sax. SAXParse Exception: cvc-type.3.1.2: Element 'body' is a simple type, so it must have no element information item [children].To turn on validation, you must request it explicitly.In this tip, I show you how to do that using the SAX API.One day, when XML:: Schema is completed I will replace this module with a wrapper around it.
