public void head(Node source, int depth)
NodeVisitorThe node may be modified (e.g. Node.attr(String), replaced Node.replaceWith(Node)) or removed
Node.remove(). If it's instanceOf Element, you may cast it to an Element and access those
methods.
head in interface NodeVisitorsource - the node being visited.depth - the depth of the node, relative to the root node. E.g., the root node has depth 0, and a child node
of that will have depth 1.public void tail(Node source, int depth)
NodeVisitorThis method has a default no-op implementation.
Note that neither replacement with Node.replaceWith(Node) nor removal with Node.remove() is
supported during tail().
