Read attribute from XML file

Question

I am trying to read XML attributes from XML file. I want to echo baadNavn.

                <?php
                $url = "https://xml.websejler.dk/da/baad/1234";
                $xml = simplexml_load_file($url);
                print_r($xml);
                echo $xml[baad][baadNavn];
                ?>

What do I wrong?

Print_r gives me:

I expect to get "Ongo Bongo" as result.

Answer 1

You can use the attributes() function on the node to get it's attributes:

$xml_str = '<xml>
    <node>
        <someTag cp="c2">content</someTag>
    </node>
</xml>';
$res = simplexml_load_string($xml_str);

$items = $res->xpath("//someTag");
var_dump((string) $items[0]->attributes()->cp);

The returned element is an SimpleXMLElement, so in order to use it I converted it to string (using the (string) cast).

Answer 2

$url = "https://xml.websejler.dk/da/baad/1234";
$xml = simplexml_load_file($url);
echo (string) $xml->baad->attributes()['baadNavn']; // Ongo Bongo
