Net xml validating reader
DTDs and XSD were normally accessed as configuration options in Simple API for XML (SAX), Document Object Model (DOM), and Java™ API for XML Processing (JAXP). Schematron might use the Transformations API for XML(Tr AX); and still other schema languages required programmers to learn still more APIs, even though they were performing essentially the same operation.
Java 5 introduced the package to provide a schema-language-independent interface to validation services.
They might also assign types like int or g Year to an element or attribute.Typically, the URL is the namespace Uniform Resource Identifier (URI) for the schema language. However, you can install additional libraries that add support for these and other schema languages.The Java programming language isn't limited to a single schema factory.You can also tell whether and how a type is derived from another type.
Beyond that, understanding the type is up to your program.The You can reuse the same validator and the same schema multiple times in series. Usually the document consumer should choose the schema, not the document producer. All other schema languages require an explicitly specified schema location. The abstract factory design pattern enables this one API to support many different schema languages and object models.
