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.
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.
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.
Most of the DOM parsers also allow you to create an in-memory DOM structure from scratch, rather than just parsing an XML to a DOM.
JAXP 1.0, then called Java API for XML Parsing, was a box office hit in the developer community, because of the pluggability layer provided by JAXP; that's what the essence of JAXP is.
Developers can write program independent of the underlying XML processor by using the JAXP APIs, and can replace the underlying XML processor by choice without even changing a single line of application code. First of all, there has been some confusion in the past about the P in JAXP: Parsing or Processing?

Thereafter, JAXP has evolved to an extent, where now it supports a lot more things (like validation against schema while parsing, validation against preparsed schema, evaluating XPath expressions, etc.,) than only parsing an XML document.
