Application output will look like below snap: package com.g2.
One of the main advantages of validation is that we can combine it with standard parsers like SAX.
DOMParser is recommended if the DOM tree structure of an XML document is required for random access and modification of the XML document.
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.An XMLSchema object represents the DOM structure of an XML schema document and is created with an XSDBuilder class object.Create an XSDBuilder object and invoke the build(Input Source) method of the XSDBuilder object to obtain an XMLSchema object.To run the application, right-click on in Application Navigator, and select Run. The validation error indicates that the title element is not expected.In this section, we shall validate the example XML document, catalog.xml, against with the DOMParser class.
