NAME

HTML::Formatter - Base class for HTML formatters

VERSION

version 2.12

SYNOPSIS

  use HTML::FormatSomething;
  my $infile  = "whatever.html";
  my $outfile = "whatever.file";
  open OUT, ">$outfile"
   or die "Can't write-open $outfile: $!\n";
  print OUT HTML::FormatSomething->format_file(
    $infile,
      'option1' => 'value1',
      'option2' => 'value2',
      ...
  );
  close(OUT);

DESCRIPTION

HTML::Formatter is a base class for classes that take HTML and format it to some output format. When you take an object of such a base class and call "$formatter-"format( $tree )> with an HTML::TreeBuilder (or HTML::Element) object, they return the appropriately formatted string for the input HTML.

HTML formatters are able to format a HTML syntax tree into various printable formats. Different formatters produce output for different output media. Common for all formatters are that they will return the formatted output when the format() method is called. The format() method takes a HTML::Element object (usually the HTML::TreeBuilder root object) as parameter.

METHODS

new

    my $formatter = FormatterClass->new(
        option1 => value1, option2 => value2, ...
    );

This creates a new formatter object with the given options.

format_file

format_from_file

    $string = FormatterClass->format_file(
        $html_source,
        option1 => value1, option2 => value2, ...
        );

Return a string consisting of the result of using the given class to format the given HTML file according to the given (optional) options. Internally it calls "SomeClass->new( ... )->format( ... )" on a new HTML::TreeBuilder object based on the given HTML file.

format_string

format_from_string

    $string = FormatterClass->format_string(
        $html_source,
        option1 => value1, option2 => value2, ...
        );

Return a string consisting of the result of using the given class to format the given HTML source according to the given (optional) options. Internally it calls "SomeClass->new( ... )->format( ... )" on a new HTML::TreeBuilder object based on the given source.

format

    my $render_string = $formatter->format( $html_tree_object );

This renders the given HTML object according to the options set for $formatter.

After you've used a particular formatter object to format a particular HTML tree object, you probably should not use either again.
