Question

此代码正常运行，当我们升级到php 5.3.10时，它停止工作并开始抛出一些非常奇怪的错误。

原始XML在w3c.org上验证没有错误，但是为了简洁和安全，我已经删除了特定网站。

XML（为简洁而编辑但在第1行产生错误）：

<AmberAlertDirective  
xmlns="http://www.hidden.com/AmberAlert"  
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://www.hidden.com/en_US/AmberAlert.xsd">
  <Directive>New</Directive>
  <AmberAlertId>9969</AmberAlertId>
  <MessageTimestamp>2012-03-27T00:35:11</MessageTimestamp>
  <AmberAlert>
    <Target>
      <State Code="OH">
      </State>
    </Target>
  </AmberAlert>
</AmberAlertDirective>

error_log中的php错误：

Answer 1

在传递给SimpleXML之前，请尝试turning Off magic_quotes或将您的XML内容放入stripslashes。

Answer 2

从您的错误中我相信您的问题在于没有注册您的命名空间。即默认命名空间。有几种方法，它只取决于你如何处理数据。

XPATH：

$xml->registerXPathNamespace('default', 'http://www.hidden.com/AmberAlert');

儿童（）：

$xml->children('http://www.hidden.com/AmberAlert');

升级到php 5.3.10并且simpleXMLelement被破坏了
