返回xpath属性

Question

我正在尝试返回“标签”属性的值，但没有成功。我被困了哈哈

$dom = new DOMDocument();
@$dom->loadHTML($source);
$xml = simplexml_import_dom($dom);
$code = $xml->xpath("//toolbarbutton");
var_dump($code);

(
    [0] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [label] => Hello World
                    [cmd] => redirect
                    [mode] => true
                )

        )

)

Answer 1

尝试使用

$attr = $code[0]->attributes();
echo $attr['label'];
