libxml-simple-perl 2.22-1 (amd64 binary) in ubuntu xenial

 The XML::Simple module provides a simple API layer on top of an underlying
 XML parsing module to maintain XML files (especially configuration
 files). Two functions are exported: XMLin() and XMLout().
 .
 The simplest approach is to call these two functions directly, but an
 optional object oriented interface allows them to be called as
 methods of an XML::Simple object. The object interface can also be
 used at either end of a SAX pipeline.
