Parser doesn t support setschema not validating

This is achieved using a implementation is the entry point to the Validation APIs.This step goes through the pluggability mechanism that has long been at the core of JAXP.All the samples are available for download from here.The major new features introduced are the following: JAXP 1.3 introduces a new schema-independent Validation Framework (called the Validation APIs).However, with the new Validation APIs, an application needs to parse a set of schemas only once. Note that it is an error to use either of the following properties: in conjunction with a non-null .Validate a SAXSource or DOMSource As we mentioned earlier, there has been fundamental shift in XML parsing and validation.Perhaps more importantly, many previously unsolvable problems can now be solved in an efficient, easy, and secure way.

Think a very patterned Diane von Furstenberg wrap dress, or a clashing, patterned blazer and pair of trousers.

This is quite useful when you are writing a schema and want to make sure that the schema conforms to the specification. W3C_XML_SCHEMA_NS_URI; Schema Factory factory = Schema Instance(language); Error Handler(new My Error Handler()); Resource Resolver( new My LSResource Resolver()); Stream Source ss = new Stream Source(new File("my Schema.xsd"))); Schema schema = Schema(ss); instance can be shared with many different parser instances, even if they are running in different threads.

You can write applications so that the same set of schema are parsed only once and the same instance is passed to different instances of the parser.

Validate XML Using Compiled Schema Before we look at this approach, let's look at how we have been doing schema validation using the schema properties that were defined in JAXP 1.2: Here is an example showing how these two properties are used in JAXP 1.3: SAXParser Factory spf = SAXParser Instance(); Namespace(true); Validating(true); SAXParser sp = SAXParser(); Property("#", " Property("#", "my Schema.xsd") ; sp.parse( attribute in the instance document to specify the schema location(s).

This approach works well, but there is a tremendous performance penalty: The specified schemas are loaded again and again for every XML document that needs to be validated! Performance gain largely depends on the ratio of the size of the XML schema to the size of the XML document. Look at the Reusing a Parser Instance section to further improve the performance.
