Description:
------------
When parsing a document with multiple / default namespaces a wrong namespace can be reported. PHP 4.3.8 shows the right result.

Reproduce code:
---------------
<?php

error_reporting(E_ALL);

$xml = <<<HEREDOC
<?xml version="1.0"?>
<x xmlns="http://x/" xmlns:y="http://y/">
    <y z="z" y:y="y" xmlns="http://a/" />
</x>
HEREDOC;

$p =& xml_parser_create_ns(null, "\n");
$vals  = array();
$index = array();
xml_parser_set_option($p, XML_OPTION_SKIP_WHITE, true);
xml_parser_set_option($p, XML_OPTION_CASE_FOLDING, false);
if (!xml_parse_into_struct($p, $xml , $vals, $index)) {
    echo xml_error_string($p);
}
xml_parser_free($p);

print_r($vals);

?>


Expected result:
----------------
The attribute y:y should be in the http://y/ namespace, this is also the result when using PHP 4.3.8

Actual result:
--------------
With PHP 5.02 the attribute y:y is in the http://a/ namespace. When the z attribute is removed the bug does not occur.
