From manual page: http://www.php.net/function.xml-set-end-namespace-decl-handler
---

Hi!

This function has the same problem that xml_start_namespace_decl_handler, the function does not expects $user_data. In the explanation appears:

HANDLING.
handler  ( resource $parser  , string $user_data  , string $prefix  )

the correct is:
handler  ( resource $parser  , string $prefix  )

and the below box of $user_data is not necessary.
----

I've looked the PHP source code of php-xml in xml.c file, and in line 1157 appears the following:

void _xml_endNamespaceDeclHandler(void *userData, const XML_Char *prefix)

but I think that "void *userData " in the php function refers to the $parser attribute, it seems me that is the start of confusion.

Regards :)

Hi Carlos

The documentation (as of writing) is correct;

For xml_set_start_namespace_decl_handler(), which calls an internal function in xml.c (_xml_startNamespaceDeclHandler) that actually performs the call to the PHP userland function, you can see that we declare a zval *args[3] and pass 3 arguments that we are going to pass to the userland handler:

args[0] = _xml_resource_zval(parser->index);
args[1] = _xml_xmlchar_zval(prefix, 0, parser->target_encoding);
args[2] = _xml_xmlchar_zval(uri, 0, parser->target_encoding);

0 = resource
1 = string (converted from XMLChar)
2 = string (converted from XMLChar)

Same is true for the xml_set_end_namespace_decl_handler() function except these arguments are passed instead:

args[0] = _xml_resource_zval(parser->index);
args[1] = _xml_xmlchar_zval(prefix, 0, parser->target_encoding);

0 = resource
1 = string (converted from XMLChar)
