public class XSLTVisitor
extends XPathVisitor
A derivation from this class can be passed to a class that implements the XSLTVisitable interface, to have the appropriate method called for each component of an XSLT stylesheet. Aside from possible other uses, the main intention is to provide a reasonable means to perform expression rewriting.
