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:

                            )

                    ) etc etc

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

Answer 1

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>";
    }
}
