Cannot access Object key “@attributes” for itunes RSS feed

Question

I'm trying to parse an itunes RSS feed by converting it to JSON via php and then inserting it with jQuery .ajax.

First is the php

<?php
     $url = "http://schoolceoshow.libsyn.com/rss";
     $fileContents = file_get_contents($url);
     $fileContents = str_replace(array("\n", "\r", "\t"), '', $fileContents);
     $fileContents = trim(str_replace('"', "'", $fileContents));
     $simpleXml = simplexml_load_string($fileContents);
     $json = json_encode($simpleXml);
     echo $json;
?>

Now the javascript

var root = location.origin + "/";

$.ajax({
url:root + "php/podcast.php",
type:"GET",
data:"json",
success:function(data){
    var dataObject = $.parseJSON(data);
    console.log(dataObject.channel.item[0].enclosure);
},
error:function(){
    console.log("failed");
}
});

What that logs out is

Object {@attributes: Object}
  @attributes: Object
    length: "25583209"
    type: "audio/mpeg"
    url: "http://traffic.libsyn.com/schoolceoshow/SchoolCEOShow-007.mp3"

My only issue here is accessing the @attributes key. How do I access a key with an @ symbol? Thanks!

Answer 1

The solution is to access the object with bracket notation. What I've added to my code is

var enclosure = dataObject.channel.item[0].enclosure;
console.log(enclosure["@attributes"]);
