    <p>PHP 5.1.2+ has an extension called <a href="http://php.net/manual/en/book.simplexml.php" rel="nofollow">SimpleXML</a> enabled by default. It's very useful for parsing well-formed XML like your example above.</p> <p>First, create a <a href="http://www.php.net/manual/en/class.simplexmlelement.php" rel="nofollow">SimpleXMLElement</a> instance, passing the XML to its constructor. SimpleXML will parse the XML for you. (This is where I feel the elegance of SimpleXML lies - SimpleXMLElement is the entire library's sole class.)</p> <pre><code>$xml = new SimpleXMLElement($yourXml); </code></pre> <p>Now, you can easily traverse the XML as if it were any PHP object. Attributes are accessible as array values. Since you're looking for tags with specific attribute values, we can write a simple loop to go through the XML:</p> <pre><code>&lt;?php $yourXml = &lt;&lt;&lt;END &lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;test&gt; &lt;required&gt; &lt;item type="binary"&gt; &lt;name&gt;The name&lt;/name&gt; &lt;url visibility="restricted"&gt;c:/temp/test/widget.exe&lt;/url&gt; &lt;/item&gt; &lt;item type="document" subtype="mytype"&gt; &lt;name&gt;document name&lt;/name&gt; &lt;url visiblity="visible"&gt;c:/temp/test.pdf&lt;/url&gt; &lt;/item&gt; &lt;/required&gt; &lt;/test&gt; END; // Create the SimpleXMLElement $xml = new SimpleXMLElement($yourXml); // Store an array of results, matching names to URLs. $results = array(); // Loop through all of the tests foreach ($xml-&gt;required[0]-&gt;item as $item) { if ( ! isset($item['subtype']) || $item['subtype'] != 'mytype') { // Skip this one. continue; } // Cast, because all of the stuff in the SimpleXMLElement is a SimpleXMLElement. $results[(string)$item-&gt;name] = (string)$item-&gt;url; } print_r($results); </code></pre> <p>Tested to be correct in <a href="http://codepad.org/DBJY2wer" rel="nofollow">codepad</a>.</p> <p>Hope this helps!</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).
