Unfortunately, the xml_set_object function does not work to solve this problem. I tried using it, and my results were the same as they were when I was not using it.
[I found that the array($this, 'function_name') method instead of 'string function_name' for the xml_set_*_handler functions worked just as well, only without this Warning message one gets from PHP 4.2.1 upon using xml_set_object($this->parser, &$this): "PHP Warning: Call-time pass-by-reference has been deprecated - argument passed by value; If you would like to pass it by reference, modify the declaration of xml_set_object(). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file. However, future versions may not support this any longer."] Still searching for an answer on this one ...
