libxml-twig-perl binary package in Ubuntu Focal amd64

 The XML::Twig module provides a way to process XML documents. It is built on
 top of XML::Parser.
 .
 The module offers a tree interface to the document, while allowing to
 output the parts of it that have been completely processed.
 .
 It allows minimal resource (CPU and memory) usage by building the
 tree only for the parts of the documents that need actual processing,
 through the use of the twig_roots and twig_print_outside_roots
 options. The finish and finish_print methods also help to increase
 performance.
 .
 XML::Twig tries to make simple things easy so it tries its best to
 takes care of a lot of the (usually) annoying (but sometimes
 necessary) features that come with XML and XML::Parser.
