Because JAXP 1.0 supported only parsing, therefore, it was called Java API for XML Parsing.

Content Handler interface and register it with the SAX parser.

A typical sequence of events reported through the callbacks could be start Document, start Element, characters, end Element, end Document, in that order.

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.

For example: Note that, even if the validation is turned off, and if the XML instance has a DOCTYPE declaration to an external DTD, the parser always tries to load that DTD.

This is done to ensure that any entity references in the XML instance (entity declarations being in the DTD) are expanded properly, which otherwise might lead to a malformed XML document, until and unless the standalone attribute on the XML declaration prolog is set to true, in which case the external DTD is ignored completely.

Every element node in the object model represents a pair of tags in the XML.

A DOM parser reads the entire XML file and creates an in-memory data structure called DOM.

start Document is called only once before reporting any other event.

Similarly, end Document is called only once after the entire XML is parsed successfully. SAXParser Factory spfactory = SAXParser Instance(); Namespace Aware(true); SAXParser saxparser = SAXParser(); //write your handler for processing events and handling error Default Handler handler = new My Handler(); //parse the XML and report events and errors (if any) to the handler saxparser.parse(new File("data.xml"), handler); DOM parsing is an object-based parsing mechanism, which generates an XML object model: an inverted tree-like data structure, which represents the XML document.

SAX parsing is an event-based, push-parsing mechanism, which generates events for the tags, the character data, and so on.
