data::format::html

Data::Format::HTML(3pm) 				User Contributed Perl Documentation				   Data::Format::HTML(3pm)

NAME

       Data::Format::HTML - Format Perl data structures into simple HTML

SYNOPSIS

	use Data::Format::HTML;

	my $f = Data::Format::HTML->new;

	my %hash = (simple => 'hash');

	# Of course it's very unlikely that you won't deal ever with this
	# kind of structure, but HTML is able to hand it all anyway :)
	my $struct = {
	       foo			       => 'bar',
	       1				       => 2,
	       'hello' 		       => 'goodbye',
	       array_ref		       => [qw/one two three/],
	       nested_hash		       => \%hash,
	       [qw/1 2/]		       => sub { die; },
	       even_more		       => { arr => {
			       1 => [2, 3, 4],
			       this_is_insane => { a => { b => { c => { d => { e => 'z'}}}}}
		       },
	       },
	};

	$struct->{'Data::Format::HTML handles it all'} = $f;

	print $f->format();

       And that will output the following insane, but possible, for the sake of showing, HTML:

       In theory you can pass any kind of Perl data structure to "format" and you will get its data HTML-formatted.
