pod::simple::simpletree
Pod::Simple::SimpleTree(3pm) User Contributed Perl Documentation Pod::Simple::SimpleTree(3pm)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 whather you have an
element node or just a text node.
The top node in the tree is "[ 'Document', \%attributes, ...subnodes... ]"
