Pod::TreeWalker - Walk a Pod tree and generate an event for each node
my $to-html = Pod::To::HTML.new(...);
Pod::TreeWalker.new( :listener($to-html) ).walk-pod($=pod);
This class provides an API for walking a pod tree (as provided by
$=pod). Each node in the tree will trigger one or more events. These events cause methods to be called on a listener object that you provide. This lets you do something with a Pod document without having to know much about the underlying tree structure of Pod.
my $walker = Pod::TreeWalker.new( :listener($object) )
The constructor expects a single named argument
:listener. This object must implement the Pod::TreeWalker::Listener API.
This method walks through a pod tree starting with the top node in
$pod. You can provide either an array of pod nodes (as stored in
$=pod) or a single top-level node (such as
Pod::Block of any sort, this method recursively descends the blocks contents and returns the concatenation of all the plain text that it finds.
