simplexml获取没有类型转换的节点值 [英] simplexml get node value without typecasting

问题描述

有没有办法从 simplexml 对象获取节点值而不转换它？

Is there any way to get a node value from a simplexml object without casting it?

$amount = (int)$item->amount;

这在我看来不是很漂亮，我在寻找一个更干净的方式，但没有找到任何东西到目前为止！

This is not very beautiful in my opinion, I'm searching for a cleaner way but did not find anything so far!

//wouldn't this be nice?
$amount = $item->amount->getValue();

提前感谢。

推荐答案

获取一个节点的值，而不必进行类型转换？当然！ ：3

Getting the value of a node without having to typecast it? Sure thing! :3

class SimplerXMLElement extends SimpleXMLElement
{
    public function getValue()
    {
        return (string) $this;
    }
}

现在你只需要使用 simplexml_load_string（）的第二个参数来获得更简单的XML元素！

Now you just have to use simplexml_load_string()'s second parameter to get even simpler XML elements!

是节点。如果你需要使用节点的值作为字符串，整数和什么不是，它将涉及typecasting在一个点或另一个，无论你是否亲自。

More seriously though, a node is a node. If you need to use the value of a node as a string, integer and what not, it will involve typecasting at one point or another, whether you do it personally or not.
