    <p>Basically, dealing with an XML feed that's not written in the nicest way (Youtube API data), and follows on from <a href="https://stackoverflow.com/questions/3163046/parsing-annoying-youtube-api-xml-feeds-with-jquery">a previous question on the topic</a>.</p> <p>Currently, there are four nodes in the file named <code>media:thumbnail</code>. Each <code>media.thumbnail</code> node has various attributes, one of which is <code>url</code>. I am only wanting to retrieve value of the first occurrence of the <code>url</code> attribute (the result being <code>http://i.ytimg.com/vi/CQP_AuT4zXQ/2.jpg</code>).</p> <p>Example;</p> <pre><code>&lt;item&gt; ... &lt;media:group&gt; ... &lt;media:thumbnail url='http://i.ytimg.com/vi/CQP_AuT4zXQ/2.jpg' height='90' width='120' time='00:04:53.500'/&gt; &lt;media:thumbnail url='http://i.ytimg.com/vi/CQP_AuT4zXQ/1.jpg' height='90' width='120' time='00:02:26.750'/&gt; &lt;media:thumbnail url='http://i.ytimg.com/vi/CQP_AuT4zXQ/3.jpg' height='90' width='120' time='00:07:20.250'/&gt; &lt;media:thumbnail url='http://i.ytimg.com/vi/CQP_AuT4zXQ/0.jpg' height='240' width='320' time='00:04:53.500'/&gt; ... &lt;/media:group&gt; ... &lt;/item&gt; </code></pre> <p>My knowledge of jQuery is still developing, and I've been able to retrieve the values of the <code>url</code> attribute for all occurrences of <code>media:thumbnail</code> using the following code:</p> <pre><code>$(this).find("[nodeName=media:thumbnail]").each(function() { $("#output").append("&lt;img src=\"" + $(this).attr("url") + "\"&gt;\n"); }); </code></pre> <p>How do I now limit this so I only grab the value of <code>url</code> for the first occurrence of <code>media:thumbnail</code>?</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.
