几乎完成了从 1.3.14 到 2.0.5 的 CakePHP 迁移（在一个我没有编写的非常大的项目上）剩下的问题之一是 XML Helper 的弃用。
2.0.5 中的新 XML 类在我以前工作的地方失败了。迁移指南指出“现在这个类不再操作数据，它是 SimpleXMLElement 的包装器” http://book.cakephp.org/2.0/en/appendices/2-0-migration-guide.html#xml
以前我使用的是：
file_put_contents($xml_file, $this->Xml->serialize($quote, array('encoding' => 'UTF-8')));
我尝试将上述内容替换为：
$xml = Xml::build($quote, array(
'encoding' => 'UTF-8',
'format' => 'attributes'));
然而，我得到的只是一个异常'XmlException'，带有消息'无效输入'。我在下面包含了一个示例数组。基本上，新的 XML 类不喜欢数组输入。应用程序的多个部分都生成复杂的 XML，并且存在相同的问题。
有没有人遇到过这个问题？我将永远调试它。
我想一个潜在的解决方法是复制旧的 Xml.php 和帮助程序，并可能制作一个插件，但如果可能的话，我更愿意让这一切正常工作。
