使用php解析XML并忽略特殊字符

我试图通过一个包含大量子属性的xml文件进行解析

其中有一些特殊字符，我的php错误日志显示了这一点

[23-Jun-2015 17:56:11 America/Denver] PHP Warning:  simplexml_load_file(): anime.xml:1: parser error : Start tag expected, '<' not found in /home/residez3/public_html/aresrelease/db/test.php on line 14

我现在感觉很笨，我发现我的xml文件没有被写入。

fclose($handle);

$xml = simplexml_load_file('anime.xml');
