xml_set_element_handler — Set up start and end element handlers
$parser
   , callable $start_element_handler
   , callable $end_element_handler
   )
   Sets the element handler functions for the XML parser.
   start_element_handler and
   end_element_handler are strings containing
   the names of functions that must exist when xml_parse()
   is called for parser.
  
parserA reference to the XML parser to set up start and end element handler functions.
start_element_handler
       The function named by start_element_handler
       must accept three parameters:
       
$parser
        , string $name
        , array $attribs
        )parsernamename, contains the name
           of the element for which this handler is called.If case-folding is in effect for this
           parser, the element name will be in uppercase letters.
          
         attribsattribs, contains an
           associative array with the element's attributes (if any).The keys
           of this array are the attribute names, the values are the attribute
           values.Attribute names are case-folded on the same criteria as
           element names.Attribute values are not
           case-folded.
          
          
           The original order of the attributes can be retrieved by walking
           through attribs the normal way, using
           each().The first key in the array was the first
           attribute, and so on.
          
         Note: Instead of a function name, an array containing an object reference and a method name can also be supplied.
end_element_handler
       The function named by end_element_handler
       must accept two parameters:
       
$parser
        , string $name
        )parsernamename, contains the name
           of the element for which this handler is called.If case-folding is in effect for this
           parser, the element name will be in uppercase letters.
          
         
       If a handler function is set to an empty string, or FALSE, the handler
       in question is disabled.
      
   Returns TRUE on success or FALSE on failure.
