php-xml-parser 1.3.6-1ubuntu1 (amd64 binary) in ubuntu xenial

 This is an XML parser based on PHPs built-in xml extension.
 It supports two basic modes of operation: "func" and "event". In "func" mode,
 it will look for a function named after each element (xmltag_ELEMENT for start
 tags and xmltag_ELEMENT_ for end tags), and in "event" mode it uses a set of
 generic callbacks.
 .
 Since version 1.2.0 there's a new XML_Parser_Simple class that makes parsing
 of most XML documents easier, by automatically providing a stack for the
 elements.
 Furthermore its now possible to split the parser from the handler object, so
 you do not have to extend XML_Parser anymore in order to parse a document with
 it.
