libjsoup-java binary package in Ubuntu Focal amd64

 Jsoup is a Java library for working with real-world HTML. It provides a very
 convenient API for extracting and manipulating data, using the best of DOM,
 CSS, and jquery-like methods.
 .
 jsoup implements the WHATWG HTML specification (http://whatwg.org/html), and
 parses HTML to the same DOM as modern browsers do.
 .
   * parse HTML from a URL, file, or string
   * find and extract data, using DOM traversal or CSS selectors
   * manipulate the HTML elements, attributes, and text
   * clean user-submitted content against a safe white-list, to prevent XSS
   * output tidy HTML
 .
 jsoup is designed to deal with all varieties of HTML found in the wild; from
 pristine and validating, to invalid tag-soup; jsoup will create a sensible
 parse tree.
