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

Perl version 5.10.0 documentation - Pod::Simple::SimpleTree
ref($node)
to see whather you have an element node or just a text node.
The top node in the tree is
[ 'Document', \%attributes,
...subnodes...
]
