    <p>I am knee deep in foreach purgatory right now trying to come up with a way to traverse this XML file (actual XML text below) with PHP(following the XML file content.) What I am trying to do is the following:</p> <ol> <li>Get all folder element names</li> <li>If the folder element has yes as a subfolder attribute, then move a level down and grab that folder element's name</li> <li>If not move on to the next folder element</li> </ol> <p>gallerylist.xml:</p> <pre><code>&lt;?xml version="1.0" encoding="ISO-8859-1"?&gt; &lt;gallerylisting exists="yes"&gt; &lt;folder subfolder="yes"&gt; Events &lt;folder subfolder="yes"&gt; Beach_Clean_2010 &lt;folder subfolder="no"&gt; Onna_Village &lt;/folder&gt; &lt;folder subfolder="no"&gt; Sunabe_Sea_Wall &lt;/folder&gt; &lt;/folder&gt; &lt;/folder&gt; &lt;folder subfolder="no"&gt; Food_And_Drink &lt;/folder&gt; &lt;folder subfolder="no"&gt; Inside &lt;/folder&gt; &lt;folder subfolder="no"&gt; Location &lt;/folder&gt; &lt;folder subfolder="no"&gt; NightLife &lt;/folder&gt; &lt;/gallerylisting&gt; </code></pre> <p>gallerylisting.php</p> <pre><code>&lt;?php $xmlref = simplexml_load_file("gallerylisting.xml"); foreach($xmlref-&gt;children() as $child) { foreach($child-&gt;attributes() as $attr =&gt; $attrVal) { print $child; if($attrVal == "yes") { foreach($child-&gt;children() as $child) { echo $child; foreach($child-&gt;attributes() as $attr =&gt; $attrVal) { if($attrVal == "yes") { foreach($child-&gt;children() as $child) { echo $child; } } } } } } } </code></pre> <p>I am...counting...5 foreach loops deep into this PHP script and I do not like it at all, plus if my folders had another subfolder, I would have to add this same</p> <pre><code>$if(attrVal=="yes")...etc. </code></pre> <p>in again and well...no! Is there anyway at all that I can avoid this. I'm new to PHP, and especially PHP and XML.</p> <p>Thanks for any help.</p>

    1. COAs you tagged this question with efficiency i will bring up this point. You don't need a "subfolder" attribute in your xml. The PHP-Library will help you find out, whether the node has children or not. If they have, use @Matt's function recursively. An you should not mix "text" elements (e.g. your folder names) with nodes. That looks a little nasty. Try a "name" attribute instead.

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.
