    <p>I have a very simple XML file:</p> <pre><code>&lt;?xml version="1.0" encoding="ISO-8859-1"?&gt; &lt;Data&gt;&lt;Day Num="4197"&gt; &lt;Date&gt;270611&lt;/Date&gt; &lt;Energy&gt;47&lt;/Energy&gt; &lt;/Day&gt; &lt;Day Num="4219"&gt; &lt;Date&gt;190711&lt;/Date&gt; &lt;Energy&gt;202&lt;/Energy&gt; &lt;/Day&gt; &lt;Day Num="4220"&gt; &lt;Date&gt;200711&lt;/Date&gt; &lt;Energy&gt;17074&lt;/Energy&gt; &lt;/Day&gt; &lt;Day Num="4221"&gt; &lt;Date&gt;210711&lt;/Date&gt; &lt;Energy&gt;11563&lt;/Energy&gt; &lt;/Day&gt; &lt;Day Num="4222"&gt; &lt;Date&gt;220711&lt;/Date&gt; &lt;Energy&gt;18178&lt;/Energy&gt; &lt;/Day&gt; &lt;Day Num="4223"&gt; &lt;Date&gt;230711&lt;/Date&gt; &lt;Energy&gt;24916&lt;/Energy&gt; &lt;/Day&gt; &lt;Day Num="4224"&gt; &lt;Date&gt;240711&lt;/Date&gt; &lt;Energy&gt;10555&lt;/Energy&gt; &lt;/Day&gt; &lt;Day Num="4225"&gt; &lt;Date&gt;250711&lt;/Date&gt; &lt;Energy&gt;12683&lt;/Energy&gt; &lt;/Day&gt; &lt;/Data&gt; </code></pre> <p>With some help on here yesterday I got it to pull out Date and Energy, but now I want to display Day Num.</p> <p>I did a print_r($xml); which shows:</p> <pre><code> SimpleXMLElement Object ( [Day] =&gt; Array ( [0] =&gt; SimpleXMLElement Object ( [@attributes] =&gt; Array ( [Num] =&gt; 4197 ) [Date] =&gt; 270611 [Energy] =&gt; 47 ) [1] =&gt; SimpleXMLElement Object ( [@attributes] =&gt; Array ( [Num] =&gt; 4219 ) [Date] =&gt; 190711 [Energy] =&gt; 202 ) </code></pre> <p>So the Num field I want is in an array, but I cannot figure out how to extract it?</p> <p>My current code is very simple, it is:</p> <pre><code>$xml = simplexml_load_file("DATA.XML"); foreach($xml-&gt;children() as $day) { list($date, $energy) = $day-&gt;children(); echo ',Date: ' . $date . ', Energy: ' . $energy . '&lt;br /&gt;'; } </code></pre> <p>How would I extract Day Num please?</p>

    1. CO`$data->Day[0]['Num']` will return the first day elements num attribute - See http://codepad.org/IY664nXm and please read http://www.php.net/manual/en/simplexml.examples-basic.php because this is explained in the manual.

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.
