Retrieving XML values from namespace elements with PHP

Question

Please could someone explain how to loop through the tags in this xml in order to echo all the elements with a d: prefix

Answer 1

As in your other question, you could use an approach with xpath:

$xml = simplexml_load_file($url);

foreach ($xml->entry as $entry) { // loop over the entries
    print_r($entry->xpath('//d:BC_3MONTH')); // gives you the actual BC_3MONTH
    print_r($entry->xpath('//d:Id')); // the actual ID
}
