HTML::FormatText::Netrik - format HTML as plain text using netrik

SYNOPSIS

Top

 use HTML::FormatText::Netrik;
 $text = HTML::FormatText::Netrik->format_file ($filename);
 $text = HTML::FormatText::Netrik->format_string ($html_string);

 $formatter = HTML::FormatText::Netrik->new;
 $tree = HTML::TreeBuilder->new_from_file ($filename);
 $text = $formatter->format ($tree);

DESCRIPTION

Top

HTML::FormatText::Netrik turns HTML into plain text using the netrik program.

http://netrik.sourceforge.net/

The module interface is compatible with formatters like HTML::FormatText, but all parsing etc is done by netrik.

See HTML::FormatExternal for the formatting functions and options, with the following caveats,

input_charset, output_charset

These charset overrides have no effect. Input might be single-byte only, and output probably follows the input (as of netrik 1.15.7).
