    <p>I wrote a recursive, expanded version that will sort by any number of attributes, in order:</p> <pre><code>//sort_xml_by_attr($simplexmlobject,array('attr_one','attr_two','attr_three')) class SortXML { public $xml; var $attr; function SortXML($xml,$attr) { $this-&gt;xml = $xml; $this-&gt;attr = $attr; } function cmp_attr($a,$b) { $a1 = (string)$a-&gt;xml[(string)$a-&gt;attr]; $b1 = (string)$b-&gt;xml[(string)$b-&gt;attr]; if (is_numeric($a1) &amp;&amp; is_numeric($b1)) { if (is_float($a1) &amp;&amp; is_float($b1)) { $a1 = (float)$a1; $b1 = (float)$b1; } else { $a1 = (int)$a1; $b1 = (int)$b1; } } if ($a1 == $b1) return 0; return ($a1 &gt; $b1) ? +1 : -1; } } function sort_xml_by_attr($xml_obj,$attr) { if (count($attr)&gt;1) { // break up array by unique values of the first attribute in the list $unique_attrs = array(); foreach ($xml_obj as $i) $unique_attrs[] = (string)$i[$attr[0]]; $unique_attrs = array_unique($unique_attrs); sort($unique_attrs); // create an array of arrays who share a unique attribute value foreach ($unique_attrs as $i) { foreach ($xml_obj as $p) { if ($p[$attr[0]] == $i) $xml_arrays[$i][] = $p; } } // remove first element to progress the recursion to the next attribute array_shift($attr); $new_array = array(); // concatenate sorted arrays foreach ($xml_arrays as $i) { $new_array = array_merge($new_array,sort_xml_by_attr($i,$attr)); } return $new_array; } else { // create wrapper objects with new comparison function foreach ($xml_obj as $i) $new_obj[] = new SortXML($i,$attr[0]); usort($new_obj,array('SortXML','cmp_attr')); foreach ($new_obj as $i) $sorted_obj[] = $i-&gt;xml; return $sorted_obj; } } </code></pre>

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.

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