libxml-tokeparser-perl binary package in Ubuntu Focal amd64

 XML::TokeParser provides a procedural ("pull mode") interface to XML::Parser
 in much the same way that Gisle Aas' HTML::TokeParser provides a procedural
 interface to HTML::Parser. XML::TokeParser splits its XML input up into
 "tokens," each corresponding to an XML::Parser event.
 .
 A token is a bless'd|"XML::TokeParser::Token" reference to an array whose
 first element is an event-type string and whose last element is the literal
 text of the XML input that generated the event, with intermediate elements
 varying according to the event type.
 .
 Each token is an object of type
 XML::TokeParser::Token|"XML::TokeParser::Token". Read
 "XML::TokeParser::Token"|"XML::TokeParser::Token" to learn what methods are
 available for inspecting the token, and retrieving data from it.
