标题中的XML解析/获取href属性

Question

I want the track-id that is listed in the href attribute.

This is the spotify xml file:

http://ws.spotify.com/search/1/track?q=Sportfreunde+Stiller+AND+track:Ein+Kompliment

This is what I tried so far:

$url = "http://ws.spotify.com/search/1/track?q=Sportfreunde+Stiller+AND+track:Ein+Kompliment";

$xml = simplexml_load_file($url);

foreach ($xml->track as $track) {
    echo $track->name."<br>";
}

How to get in the upper hierarchy?

This is the desired output: spotify:track:3ptJBraFGtaeprD4BHmTfV . In my code I just put the name of the track in the output so that you can see that I am in the wrong hierarchy.

Answer 1

You can use $track->attributes() instead of $track->name, it will output the value in the href attribute.

Ex:

<?php
$url = "http://ws.spotify.com/search/1/track?q=Sportfreunde+Stiller+AND+track:Ein+Kompliment";

$xml = simplexml_load_file($url);

foreach ($xml->track as $track) {
    echo $track->attributes() . "<br>";
}
?>

Answer 2

do print_r($xml) and give what you get

It worked fine for me I got name or result like
