    <p>To get an array of parents / children, you may use :</p> <pre><code>&lt;?php $content = file_get_contents('http://www.fluffyduck.com.au/sampleXML.txt'); $xml = new SimpleXMLElement($content); $users = array (); myUserReader($xml-&gt;user, $users); function myUserReader($node, &amp;$users) { if (array_key_exists("{$node['id']}", $users) === false) { $users["{$node['id']}"] = array (); } if (isset($node-&gt;user)) { for ($key = 0; ($key &lt; $node-&gt;user-&gt;count()); $key++) { $user = $node-&gt;user[$key]; if (!in_array("{$node['id']}", $users["{$node['id']}"])) { $users["{$node['id']}"][] = "{$user['id']}"; } myUserReader($user, $users); } } } foreach ($users as $parent =&gt; $children) { echo "{$parent}: " . implode(", ", $children) .

    1. COI checked your code with foreach... and there is no inf. loop. I even check with adding parameter $i to function to check number of sub-item.. still only 5 deeper calls.

    3. COHi Ninsuo, this is the closest i've seen to solving this problem, however it does not show the recursive ID's, there was 147 userID's but not all displayed above. For example, ID#62 has a child #64, which has a child #66, which has a child #67, which has a child #67, which has a child #68, which has child #70 and then #72, then #73 finish with #75. That is one of the tree's, I'm not sure if it is malformed xml it displays fine with Flash code but i'm not fluent in flash :(

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.
