【问题描述】：
我在解析以下 XML 字符串时遇到了困难。
使用SimpleXMLElement 或simplexml_load_string 时收到许多错误。
我正在运行 PHP 版本 5.5.20。
<?xmlversion="1.0"encoding="utf-8"?>
<Responsetype="NAK">
<ResponseCode>231</ResponseCode>
<Description>Billingstate/provinceisrequired.</Description>
<Reference>VSTMUAS:060215CJM-12</Reference>
<TransactionID>1433251975406510979</TransactionID>
<ProcessingTime>0.590634</ProcessingTime>
</Response>
当我运行以下代码时：
$xml = simplexml_load_string($myXMLData);
print_r($xml);
我收到以下错误：

请帮助我理解我做错了什么。
谢谢，

嗯，它看起来格式不正确。打开
标记在哪里？ -
我同意，它的格式不正确。这是来自外部来源的回应，不幸的是我无法控制他们发回给我的内容。但是，我可以使用一些 php 字符串操作来以正确的形式获取它。我是一些人所说的 XML 新手，所以如果有人可以告诉我表单应该如何，我可以在我的代码中进行这些更改。附带说明一下，我确实在我的帖子之前添加了
<Response>标签，我没有注意到上面显示的错误有任何变化，所以我认为这不是问题。 -
您没有做错任何事情，这就是您从字符串创建
SimpleXMLElement对象的方式。但是字符串不适合转换为 XML 对象，您应该清理它并仔细阅读返回的错误，它们非常简单
