There are two xml-files.

<?xml version="1.0" encoding="utf-8" ?>

and

<?xml version="1.0" encoding="utf-8" ?>

and the sample code:

<?php
    require_once 'Zend/Config.php';
    require_once 'Zend/Config/Xml.php';
    
    $config = new Zend_config_xml('/path/to/config.xml');
    foreach ($config->files->file as $value)
        echo 'id: '.$value->id.'
location: '.
            htmlspecialchars($value->location).'';
?>

If the {{/path/to/config.xml}} to substitute {{config1.xml}}, then everything works correctly. But if you substitute {{config2.xml}} error

Notice: Trying to get property of non-object in D:\www\index.php on line 7

How can I iterate all items {{file}}, if their number is not known in advance (one or more than one)?
