从PHP SimpleXML节点获取实际值 [英] Getting actual value from PHP SimpleXML node

问题描述

$value = $simpleXmlDoc->SomeNode->InnerNode;

实际上将一个simplexml对象分配给$ value而不是InnerNode的实际值.

actually assigns a simplexml object to $value instead of the actual value of InnerNode.

如果我这样做:

$value = $simpleXmlDoc->SomeNode->InnerNode . "\n";

我得到了价值.无论如何要获得实际值而不会显得笨拙. "\n"?

I get the value. Anyway of getting the actual value without the clumsy looking . "\n"?

推荐答案

根据需要键入任意类型(并且有意义...).通过串联，您可以隐式转换为字符串，所以

Cast as whatever type you want (and makes sense...). By concatenating, you're implicitly casting to string, so

$value = (string) $xml->someNode->innerNode;
