Description:
------------
Namespace support by the xml_* functions is broken in PHP5 latest snapshot (works fine in PHP4).

Reproduce code:
---------------
<?php
function startElement($parser,$name,$attribs) {
    echo $name . "\n";
}

function endElement($parser,$name) {
}

$parser = xml_parser_create_ns("UTF-8","@");
xml_set_element_handler($parser,'startElement','endElement');
xml_parser_set_option($parser,XML_OPTION_CASE_FOLDING,0);
xml_parse($parser,
          "<foo:a xmlns:foo=\"http://example.com/foo\" xmlns:bar=\"http://example.com/bar\"><bar:b /></foo>\n");
xml_parser_free($parser);
?>


Expected result:
----------------
PHP 4.3.3 gives output:

http://example.com/foo@a
http://example.com/bar@b


Actual result:
--------------
http://example.com/foo:a
bar:b
