DESCRIPTION
HTML::ExtractContent is a module for extracting content from HTML with scoring heuristics. It guesses which block of HTML looks like content according to scores depending on the amount of punctuation marks and the lengths of non-tag texts. It also guesses whether content end in the block or continue to the next block.

$extractor->extract($html)->as_text;
Returns extracted content as a plain text. All tags are eliminated.
- as_html
-
$extractor->extract($html)->as_html;
Returns extracted content as an HTML text. Note that the returned text is neither fully tagged nor valid HTML. It doesn't contain tags such as <html> and it may have block tags that are not closed, or closed but not opened. This method is intended for the case that you need to analyse link tags in the text for example.
