DESCRIPTION
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 Pod::Simple 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.
METHODS
At the end of the parse, call "$parser->root" to get the tree's top
node.
Tree Contents
Every element node in the parse tree is represented by an arrayref of
the form: "[ elementname, \%attributes, ...subnodes... ]". See the
example tree dump in the Synopsis, above.
Every text node in the tree is represented by a simple (non-ref) string
scalar. So you can test "ref($node)" to see whether you have an
element node or just a text node.
The top node in the tree is "[ 'Document', \%attributes, ...subnodes...
]"
