Java code for validating xml against dtd hard dating

In the context of Extensible Markup Language (XML), validation normally involves writing a detailed specification for the document's contents in any of several schema languages such as the World Wide Web Consortium (W3C) XML Schema Language (XSD), RELAX NG, Document Type Definitions (DTDs), and Schematron.

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.

This section looks at the process of XML Schema validation.

Although a full treatment of XML Schema is beyond the scope of this tutorial, this section shows you the steps you take to validate an XML document using an XML Schema definition.

Configure Java APIs (SAX, DOM, dom4j, XOM) using JAXP 1.3 to validate XML Documents with DTD and Schema(s).

Many Java XML APIs provide mechanisms to validate XML documents, the JAXP API can be used for most of these XML APIs but subtle configuration differences exists.This is the reason why (most of the) XML parser implementations do not support XML Namespaces by default, to handle the validation of XML documents with namespaces correctly it is therefore necessary to configure the underlying parsers to provide support for XML Namespaces.) as defined below has been used in the code examples to validate the input document.This package is also available in Java 1.3 and later when you install JAXP 1.3 separately.Among other products, an implementation of this library is included with Xerces 2.8. If you validate in multiple threads simultaneously, make sure each one has its own However, normally this isn't what you want. It enables you to quickly check that input is roughly in the form you expect and quickly reject any document that is too far away from what your process can handle.
