Most of the standard node handlers, and the specialized interfaces for different kinds of node, have been withdrawn: they can be recreated if necessary as part of the application.</p> <h1>Handler interfaces</h1> <p>The top-level handler interface is called NodeHandler. This defines the processing of any kind of node: elements, attributes, and character content. This interface is now in package com.icl.saxon.</p> <p>Below this level is the abstract class ElementHandler and the class ElementHandlerBase. You can define your own handlers as subclasses of ElementHandlerBase.</p> <h2>The ElementHandler interface</h2> <p>The class ElementHandlerBase is provided as an element handler that does nothing, other than calling applyTemplates() to process its children. Your own element handlers will generally be subclasses of ElementHandlerBase.</p> <p>There is one method you can override: startElement(). It is called when an element node is to be processed. There are two arguments, the ElementInfo representing the element node, and the Context object. The element will always be the current node (and also the context node) accessible via the Context object. <p align="center"><i>Michael H.
