libxml-treebuilder-perl binary package in Ubuntu Xenial armhf

 XML::Treebuilder uses XML::Parser to make XML document trees constructed of
 XML::Element objects (and XML::Element is a subclass of HTML::Element adapted
 for XML).
 .
 XML::TreeBuilder is meant particularly for people who are used to
 the HTML::TreeBuilder / HTML::Element interface to document trees, and who
 don't want to learn some other document interface like XML::Twig or XML::DOM.
