在php中解析XML问题

Question

我调用委托连接API并将其作为响应接收。

$xml_response = simplexml_load_file($xml_response);
exit($xml_response);

如果我这样做了

  $xml = new SimpleXMLElement($xml_response);

我收到一个应用程序错误。(不确定如何找出这是什么错误，我可以在哪里设置要显示此部件的错误代码？)

Answer 2

我假设你使用的是SimpleXML。

这部分永远不会起作用：$item->cj-api->，-是运算符。如果您使用的是SimpleXML，请尝试{'cj-api'}。

更核心的问题是，由于没有cj-api元素，$item->cj-api将无法工作。这是不需要寻址的根节点。请参阅http://www.php.net/manual/en/simplexml.examples-basic.php上的示例
