I'll submit one more bug in this area shortly. Test script: --------------- <?php $indent = ''; $parser = xml_parser_create_ns('UTF-8'); xml_set_element_handler($parser, function($self, $name, $attributes){ global $indent; print "{$indent}{$name} " . json_encode($attributes, 832) . "\n"; $indent .= "\t"; }, function($self, $name){ global $indent; $indent = substr($indent, 0, -1); print "{$indent}/{$name}\n"; }); xml_set_character_data_handler($parser, function($self, $data){ global $indent; if($text = trim($data)) print "{$indent}#text: {$text}\n"; }); xml_parse($parser, '<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE x [ <!ENTITY pic PUBLIC "image.gif" "http://example.org/image.gif"> ]> <p>&pic;</p>', true); // Expecting at least 'Undeclared entity error' (entity was declared for a different root tag). print xml_error_string(xml_get_error_code($parser)) . "\n"; ?> Expected result: ---------------- I would expect "Undeclared entity error" at the very least. Optimally "Mismatched tag" (wrong root tag). Actual result: -------------- "No error". ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71593&edit=1
