public class ElemTemplateElement extends UnImplNode implements PrefixResolver, java.io.Serializable, ExpressionNode, WhitespaceStrippingElementMatcher, XSLTVisitable
An instance of this class represents an element inside an xsl:template class. It has a single "execute" method which is expected to perform the given action on the result tree. This class acts like a Element node, and implements the Element interface, but is not a full implementation of that interface... it only implements enough for basic traversal of the tree.- See Also:
