simplexml_load_file不适用于某些xml [重复]

这个问题已经在这里有了答案：

• 参考-如何在SimpleXML中处理名称空间（带有冒号的标记和属性）？ 1个答案

我有一条基本的通用行来解析文件中的xml。 问题是XML 2可以很好地解析，但是XML 1返回NULL。 我检查了所有错误，仔细检查了所有内容，还没弄清楚。

还尝试了file_contents，但仍然无法正常工作。

$xml =(simplexml_load_file($data, 'SimpleXMLElement', LIBXML_NOCDATA));

Answer 1

我认为对于xml 1，您应该将名称空间添加到msg simplexml_load_file中 ，如下所示：

$xml =simplexml_load_file($data, 'SimpleXMLElement', LIBXML_NOCDATA, "urn:xmlns:SSE-HomeServices:Messages:Inbound");

您也可以从代码中删除一组括号。
