NAME

Pod::Simple::SimpleTree -- parse Pod into a simple parse tree

SYNOPSIS

  % cat ptest.pod

  =head1 PIE

  I like B<pie>!

  % perl -MPod::Simple::SimpleTree -MData::Dumper -e \
     "print Dumper(Pod::Simple::SimpleTree->new->parse_file(shift)->root)" \
     ptest.pod

  $VAR1 = [
            'Document',
            { 'start_line' => 1 },
            [
              'head1',
              { 'start_line' => 1 },
              'PIE'
            ],
            [
              'Para',
              { 'start_line' => 3 },
              'I like ',
              [
                'B',
                {},
                'pie'
              ],
              '!'
            ]
          ];

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... ]"
