This class is of interest to people writing a Pod processor/formatter.
This class takes Pod and parses it, returning a parse tree made just of arrayrefs, and hashrefs, and strings.
This is a subclass of the Pod::Simple manpage and inherits all its methods.
This class is inspired by XML::Parser's ``Tree'' parsing-style, although it doesn't use exactly the same LoL format.
At the end of the parse, call $parser->root
to get the
tree's top node.
Every element node in the parse tree is represented by an arrayref of
the form: [ elementname, \%attributes, ...subnodes... ]
.
See the example tree dump in the Synopsis, above.
Every text node in the tree is represented by a simple (non-ref)
string scalar. So you can test ref($node)
to see whether you have
an element node or just a text node.
The top node in the tree is [ 'Document', \%attributes,
I<...subnodes...> ]
