Validating schema sax start dating again
Elements and attributes are declared to be of type int, double, date, duration, person, Phone Number, or anything else you can imagine.The Java Validation API includes a means to report such types, although it's surprisingly independent of the rest of the package. This simple interface, summarized in Listing 5, tells you the local name and namespace URI of a type.The validator can create such type-augmented documents and write them onto a This procedure can't transform an arbitrary source into an arbitrary result.It doesn't work at all for stream sources and results.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.
This protocol is frequently used by servlets and network-oriented programs that need to transmit and receive XML documents, because it is the fastest and least memory-intensive mechanism that is currently available for dealing with XML documents, other than the Streaming API for XML (St AX).The default response from a schema is to throw a to receive more detailed information about the document's problems.For example, suppose you want to log all validation errors, but you don't want to stop processing when you encounter one.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. 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.
