    <p>I'm trying to extract several attributes from an XML file generated by a piece of software but I'm having no luck.</p> <p>The code I have so far looks like this;</p> <pre><code>$xml_feed_url = 'http://localhost/rest/getNowPlaying.view?u=USERNAMEt&amp;p=PASSWORD&amp;v=1.8.0&amp;c=test'; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $xml_feed_url); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $xml = curl_exec($ch); curl_close($ch); echo $xml; </code></pre> <p>This code successfully outputs the following XML file; </p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;subsonic-response xmlns="http://subsonic.org/restapi" status="ok" version="1.8.0"&gt; &lt;nowPlaying&gt; &lt;entry id="1805" parent="1798" title="Too Close" album="The Lateness Of The Hour" artist="Alex Clare" isDir="false" coverArt="1798" created="2012-05-22T13:12:29" duration="256" bitRate="320" track="4" discNumber="1" year="2011" genre="Pop" size="10283678" suffix="mp3" contentType="audio/mpeg" isVideo="false" path="Alex Clare/The Lateness Of The Hour/Alex Clare - Too Close.mp3" albumId="50" artistId="14" type="music" username="RestClient" playerId="8" minutesAgo="0"/&gt; &lt;entry id="33664" parent="33642" title="Hot Ride" album="Always Outnumbered, Never Out Gunned" artist="The Prodigy" isDir="false" coverArt="33642" created="2012-05-10T00:31:16" duration="276" bitRate="128" track="5" discNumber="1" year="2004" genre="Other" size="5135448" suffix="mp3" contentType="audio/mpeg" isVideo="false" path="The Prodigy/Always Outnumbered, Never Out Gunned/The Prodigy - Hot Ride.mp3" albumId="2064" artistId="635" type="music" username="Revenant" playerId="6" playerName="test" minutesAgo="3"/&gt; &lt;/nowPlaying&gt; &lt;/subsonic-response&gt; </code></pre> <p>I'm able to successfully extract specific attributes using a foreach loop (below), but I'm looking to extract specific multiple attributes from one user rather than them all.</p> <pre><code>foreach($xml-&gt;children()-&gt;children() as $second_gen){ echo "User: ".$second_gen['username']; echo "Artist: ".$second_gen['artist']; echo "Title: ".$second_gen['title']; echo "Album: ".$second_gen['album']; </code></pre> <p>Any ideas would be appreciated. Thanks.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
