Class ElementOverNodeInfo

  • All Implemented Interfaces:
    org.w3c.dom.Element, org.w3c.dom.Node

    public class ElementOverNodeInfo
    extends NodeOverNodeInfo
    implements org.w3c.dom.Element
    This class is an implementation of the DOM Element class that wraps a Saxon NodeInfo representation of an element node.

    The class provides read-only access to the tree; methods that request updates all fail with an UnsupportedOperationException.

    Note that contrary to the DOM specification, this implementation does not expose namespace declarations as attributes.
