Validating xml sax parser

Therefore, it becomes extremely important to always register a meaningful error handler while SAX parsing an XML document.If the application needs to be informed of the parsing events (and process it), it must implement the sax.If the DOM parser is W3C compliant, then, the DOM created is a W3C DOM, which can be traversed or modified using the org.w3APIs.

Unfortunately, the W3C XSL-T specification does not provide any APIs for transformation.

Therefore, the JAXP 1.1 Expert Group (EG) introduced a set of APIs called Transformation API for XML (Tr AX) in JAXP 1.1, and since then, JAXP is called Java API for XML Processing.

July 6, 2005 Rahul Srivastava After the first release of the W3C XML 1.0 recommendation in early 1998, XML started gaining huge popularity.

Sun Microsystems Inc., at that time had just formalized the Java Community Process (JCP), and the first version of JAXP (JSR-05) was made public in early 2000, supported by industry majors like (in chronological order) BEA Systems, Fujitsu Limited, Hewlett-Packard, IBM, Netscape Communications, Oracle, and Sun Microsystems, Inc.

Document Builder Factory dbfactory = Document Builder Instance(); Namespace Aware(true); Document Builder domparser = Document Builder(); //parse the XML and create the DOM Document doc = domparser.parse(new File("data.xml")); //to create a new DOM from scratch - //Document doc = Document(); //once you have the Document handle, then you can use //the org.w3* APIs to traverse or modify the DOM... Often people think that DTD is something alien because it has a different syntax than XML, but DTD is an integral part of W3C XML 1.0.

If an XML instance document has a DOCTYPE declaration, then to turn on validation against DTD, while parsing XML, you need to set the validating feature to true using the set Validating method on the appropriate factory.

The acceptable value for this property must be one of the following: SAXParser Factory spfactory = SAXParser Instance(); Namespace Aware(true); //turn the validation on Validating(true); //set the validation to be against WXS Property(" schema Language", " //set the schema against which the validation is to be done Property(" schema Source", new File("myschema.xsd")); W3C XSL-T defines transformation rules to transform a source tree into a result tree.

A transformation expressed in XSL-T is called a stylesheet.

JAXP supports Object-based and Event-based parsing. In Object-based, only W3C DOM parsing is supported so far.
