NodeVisitor
The 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 NodeVisitor
source
- 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)
NodeVisitor
This method has a default no-op implementation.
Note that neither replacement with Node.replaceWith(Node)
nor removal with Node.remove()
is
supported during tail()
.
