    <p>I am looping through a XML file with SimpleXML and trying to pull a specific piece of data (specifically, the <strong><em>series->displayname</em></strong> attribute) from the Previous and Next nodes each time.</p> <p><strong>Here is a sample of the XML structure:</strong></p> <pre><code>&lt;comic&gt; &lt;id&gt;117&lt;/id&gt; &lt;index&gt;1&lt;/index&gt; &lt;mainsection&gt; &lt;pagecount&gt;33&lt;/pagecount&gt; &lt;series&gt; &lt;displayname&gt;Amazing Story&lt;/displayname&gt; &lt;sortname&gt;Amazing Story&lt;/sortname&gt; &lt;/series&gt; &lt;/mainsection&gt; &lt;/comic&gt; &lt;comic&gt; &lt;id&gt;102&lt;/id&gt; &lt;index&gt;1&lt;/index&gt; &lt;mainsection&gt; &lt;pagecount&gt;33&lt;/pagecount&gt; &lt;series&gt; &lt;displayname&gt;Fantastic Tale&lt;/displayname&gt; &lt;sortname&gt;Fantastic Tale&lt;/sortname&gt; &lt;/series&gt; &lt;/mainsection&gt; &lt;/comic&gt; &lt;comic&gt; &lt;id&gt;85&lt;/id&gt; &lt;index&gt;1&lt;/index&gt; &lt;mainsection&gt; &lt;pagecount&gt;33&lt;/pagecount&gt; &lt;series&gt; &lt;displayname&gt;The Great Tale&lt;/displayname&gt; &lt;sortname&gt;The Great Tale&lt;/sortname&gt; &lt;/series&gt; &lt;/mainsection&gt; &lt;/comic&gt; </code></pre> <p><strong>And here is a sample of the structure I am using in the loop:</strong></p> <pre><code>$prevIssue = $comic-&gt;xpath('preceding-sibling::*')-&gt;mainsection-&gt;series-&gt;displayname; $nextIssue = $comic-&gt;xpath('following-sibling::*')-&gt;mainsection-&gt;series-&gt;displayname; echo ' &lt;li class="issue" id="' . $seriesCat . '"&gt; &lt;h3&gt;' . $comicSeriresName . '&lt;/h3&gt; &lt;div id="details"&gt; &lt;span id="publisher"&gt;' . $comicPublisher . '&lt;/span&gt;&lt;br&gt; The last series was called "' . $prevIssue . '&lt;br&gt; The next series is called "' . $nextIssue . '&lt;br&gt; &lt;/div&gt; &lt;/li&gt;'; </code></pre> <p>However, the 'nextIssue' and 'prevIssue' variables are not working. They are returning a blank result. What am I doing wrong?</p> <p>Any guidance is greatly appreciated.</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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
