I've got some xml I'm trying to format with the simplexml_load_string function. See below. I can grab the "leader" with the following:
$xml = simplexml_load_string($rec);
//print_r($xml);
echo $xml->leader;
BUT, let's say I wanted the "subfield" of the element with the tag=010. How would I get this? Any help is appreciated. I'm very much a newbie, but am learning as I go.
