handler
     
       handler is a string containing the name of a
       function that must exist when  xml_parse() is called
       for parser.
      
       The function named by handler must accept
       two parameters:
       
$parser
        , string $data
        )parser
         data
         data, contains
           the character data as a string.
          
         Character data handler is called for every piece of a text in the XML document. It can be called multiple times inside each fragment (e.g. for non-ASCII strings).
       If a handler function is set to an empty string, or FALSE, the handler
       in question is disabled.
      
Note: Instead of a function name, an array containing an object reference and a method name can also be supplied.
   Returns TRUE on success or FALSE on failure.
