Method Detail

head

public void head(Node node,
                 int depth)

Description copied from interface: NodeVisitor

Callback for when a node is first visited.

The node may be modified (e.g. Node.attr(String) or replaced Node.replaceWith(Node)). If it's instanceOf Element, you may cast it to an Element and access those methods.

Note that nodes may not be removed during traversal using this method; use NodeTraversor.filter(NodeFilter, Node) with a NodeFilter.FilterResult.REMOVE return instead.

Specified by:

head in interface NodeVisitor

Parameters:

node - 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.

tail

public void tail(Node node,
                 int depth)

Description copied from interface: NodeVisitor

Callback for when a node is last visited, after all of its descendants have been visited.

Note that replacement with Node.replaceWith(Node) is not supported in tail.

Specified by:

tail in interface NodeVisitor

Parameters:

node - 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.
