html::formattext5.18

HTML::FormatText(3)					User Contributed Perl Documentation				       HTML::FormatText(3)

NAME

       HTML::FormatText - Format HTML as plaintext

VERSION

       version 2.11

SYNOPSIS

	   use HTML::TreeBuilder;
	   $tree = HTML::TreeBuilder->new->parse_file("test.html");

	   use HTML::FormatText;
	   $formatter = HTML::FormatText->new(leftmargin => 0, rightmargin => 50);
	   print $formatter->format($tree);

       or, more simply:

	   use HTML::FormatText;
	   my $string = HTML::FormatText->format_file(
	       'test.html',
	       leftmargin => 0, rightmargin => 50
	       );

DESCRIPTION

       HTML::FormatText is a formatter that outputs plain latin1 text. All character attributes (bold/italic/underline) are ignored. Formatting of
       HTML tables and forms is not implemented.

       HTML::FormatText is built on HTML::Formatter and documentation for that module applies to this - especially "new" in HTML::Formatter,
       "format_file" in HTML::Formatter and "format_string" in HTML::Formatter.

       You might specify the following parameters when constructing the formatter:

       leftmargin (alias lm)
	   The column of the left margin. The default is 3.

       rightmargin (alias rm)
	   The column of the right margin. The default is 72.
