How to iterate through XML values that are a SimpleXMLElement Object - php

Question

I have an XML stream parsed to a SimpleXMLElement Object and I am trying to iterate though the available records to use as values in a PHP page.
The parent node of [listing] currently exists twice as there are two records in the test XML (listing[0] and listing[1])
But I can not get this to work like shown on the "Basic SimpleXML usage" from the PHP Manual
<?php
$xml = simplexml_load_file('http://feed.postlets.com/Burndog/6458ec1af54f632');
This works to provide the first listing title element value:
$value1 = $xml->listing[0]->title;
echo ' here:' . $value1;
This fails to iterate through the available values:
foreach ($xml->listing->title as $title) {
echo $title;
}
?>
values from a print_r:

Then what will it take to loop through the elements for pictures as there is more than one?
Thanks!

As you can see in your print_r output, the 'listing' field of the XML-Object is the array, not the title. So what you have to do is iterate through the listings and print out each listings title:
foreach ($xml->listing as $listing)
{
echo $listing->title;
}
To print out the pictures you'd do something like this:
foreach ($xml->listing as $listing)
{
echo "Title: " . $listing->title . "<br>";
foreach ($listing->photos->children() as $child)
{
echo $child . "<br>";
}
}
