20.5. Converting HTML to ASCII

20.5.1. Problem

You want to convert an HTML file into formatted, plain ASCII. For example, you want to mail a web document to someone.

20.5.2. Solution

If you have an external formatter like lynx, call an external program:

$ascii = `lynx -dump $filename`;

If you want to do it within your program and don't care about the things that the HTML::FormatText formatter doesn't yet handle well (tables and frames):

use HTML::FormatText 3;
$ascii = HTML::FormatText->format_file(
  $filename,
  leftmargin => 0, rightmargin => 50
);

20.5.3. Discussion

These examples both assume the HTML is in a file. If your HTML is in a variable, you need to write it to a file for lynx to read. With HTML::FormatText, use the format_string( ) method:

use HTML::FormatText 3;
$ascii = HTML::FormatText->format_string(
  $filename,
  leftmargin => 0, rightmargin => 50
);

If you use Netscape, its "Save as" option with the type set to "Text" does the best job with tables.
