When relate to the following codes:

xml_parse_into_struct($p, $xml, $vals, $index);
xml_parser_free($p);

The arrow symbol are missing, this is Bug of libxml2 with php,

when using PHP <= 5.2.6 with libxml2 >= 2.6.32.

This is due to an intentional change in the behaviour of libxml2 after version 2.6.32. Some sites suggest reverting to libxml2-2.6.30 – while this works as a temporary solution, it is no longer necessary or advisable.

PHP 5.2.7 or higher works with the new behaviour of libxml2 ( see: http://bugs.php.net/bug.php?id=45996 ). Simply upgrading PHP corrects the problem.

Now replace these special characters with HTML Entity. And can be rightly treated by libxml2.

Do the following repacement before parser the xml can resolve this problem:

$xml =str_replace(“<”,”<”,$xml);
$xml =str_replace(“>”,”>”,$xml);
$xml =str_replace(“&”,”&”,$xml);
