PHP Bug Type: XML related
Bug description: xml_get_current_byte_index inside character data handler
returns wrong offset
Description:
------------
Byte index returned by xml_get_current_byte_index() call in character data
handler, points to different locations of XML source, based on character
data being parsed.
If parsed string passed as second argument to handler starts with ASCII
non-white space character, byte index is offset to location before parsed
string.
If parsed string starts with white space, or UTF-8 character, it points
after parsed string.
To keep consistency with other handlers, it should return offset to
location after parsed string, in all cases.
Reproduce code:
---------------
$xml = '<R><N>before</N><N>'
.html_entity_decode('§', ENT_COMPAT, 'UTF-8')
.'after</N><N> after</N>before </R>';
function cdata ($p, $cdata) {
global $xml;
$off = xml_get_current_byte_index($p);
echo 'CDATA: "',
htmlentities($cdata, ENT_COMPAT, 'UTF-8'), '"', PHP_EOL,
'AFTER-INDEX: "',
htmlentities(substr($xml, $off), ENT_COMPAT, 'UTF-8'), '"',
PHP_EOL;
}
$p = xml_parser_create('UTF-8');
xml_set_character_data_handler($p, 'cdata');
xml_parse($p, $xml, true);
xml_parser_free($p);
Expected result:
----------------
CDATA: "before"
AFTER-INDEX: "</N><N>§after</N><N> after</N>before </R>"
CDATA: "§after"
AFTER-INDEX: "</N><N> after</N>before </R>"
CDATA: " after"
AFTER-INDEX: "</N>before </R>"
CDATA: "before "
AFTER-INDEX: "</R>"
Actual result:
--------------
CDATA: "before"
AFTER-INDEX: "before</N><N>§after</N><N> after</N>before </R>"
CDATA: "§after"
AFTER-INDEX: "</N><N> after</N>before </R>"
CDATA: " after"
AFTER-INDEX: "</N>before </R>"
CDATA: "before "
AFTER-INDEX: "before </R>"
