Bug description: Problem assigning multiple objects with XML parser within
them to one variable
Description:
------------
When assigning multiple times to ane variable an object which contains a
XML parser, there is a problem when the xml_parse is called. The parser
can not call the registered handlers.
The problem can be avoided if the variable is unset before the second
call, or using $doc1 =& new xml_doc() for every assignment.
Reproduce code:
---------------
<?
class xml_doc
{
function xml_doc()
{
$this->res = xml_parser_create_ns();
xml_set_object($this->res,$this);
xml_set_element_handler($this->res,'start_element','end_element');
}
function load_string($string)
{
xml_parse($this->res,$string);
}
function start_element()
{
}
function end_element()
{
}
}
$str = '<?xml version="1" encoding="UTF-8"
standalone="yes"?><root></root>';
$doc1 = new xml_doc();
$doc1->load_string($str);
//unset($doc1);//this solves the problem
//or using $doc1 =& new xml_doc(); in every assignment
$doc1 = new xml_doc();
$doc1->load_string($str);
?>
Expected result:
----------------
Nothing really... it is too simple to do real parsing.
Actual result:
--------------
Warning: xml_parse() [function.xml-parse.html]: Unable to call handler
start_element() in file.php on line 13
Warning: xml_parse() [function.xml-parse.html]: Unable to call handler
end_element() in file.php on line 13
