Java code for validating xml against dtd

Two things must be understood about the validating parser: method on white space that it knows to be irrelevant.From the standpoint of an application that is interested in processing only the XML data, that is a good thing because the application is never bothered with white space that exists purely to make the XML file readable.

This section examines the validating parser to find out what happens when you use it to parse the sample program.Because JAXP-compliant parsers are not namespace-aware by default, it is necessary to set the property for schema validation to work.In addition to the error handling described in Setting up Error Handling, there is one error that can occur when configuring the parser for schema-based validation.After you have learned more about namespaces, you will see how to use XML Schema to validate complex documents that do use them.Those ideas are discussed in Validating with Multiple Namespaces in Document Object Model.To be notified of validation errors in an XML document, the parser factory must be configured to create a validating parser, as shown in the preceding section.

In addition, the following must be true: Note - The parser factory must be configured to generate a parser that is namespace-aware as well as validating. More information about namespaces is provided in Document Object Model but for now, understand that schema validation is a namespace-oriented process.uses the non-validating parser by default, but it can also activate validation.Activating validation allows the application to tell whether the XML document contains the right tags or whether those tags are in the right sequence.The Java XML implementation does so whenever the DTD makes it possible.The program is configured to take additional arguments when it is started, which tell it to implement no validation, DTD validation, XML Schema Definition (XSD) validation, or XSD validation against a specific schema source file.On the other hand, if you are writing an application that filters an XML data file and if you want to output an equally readable version of the file, then that white space would no longer be irrelevant: it would be essential.
