I'm trying to parse out the following response:
SimpleXMLElement Object (
[responseType] => SimpleXMLElement Object (
[inputConceptName] => aspirin [inputKindName] => % )
[groupConcepts] => SimpleXMLElement Object (
[concept] => Array (
[0] => SimpleXMLElement Object (
[conceptName] => ASPIRIN
[conceptNui] => N0000145918
[conceptKind] => DRUG_KIND )
[1] => SimpleXMLElement Object ( #
[conceptName] => Aspirin
[conceptNui] => N0000006582
[conceptKind] => INGREDIENT_KIND )
) ) )
in PHP. I have it stored as a curl string:
$xml = simplexml_load_string($data);
print_r($xml);
How do I get just the conceptNui of the first object as a PHP variable?

Take a look at the documentation, it give simple example to understand the friendly syntax to extract the data :
http://www.php.net/manual/en/simplexml.examples-basic.php
In your case, it could be :
$xml->groupConcepts->concept[0]->conceptNui
As your structure is
SimpleXMLElement Object (
[responseType] => SimpleXMLElement Object (
[inputConceptName] => aspirin
[inputKindName] => % )
[groupConcepts] => SimpleXMLElement Object (
[concept] => Array ([0] => SimpleXMLElement Object (
[conceptName] => ASPIRIN
[conceptNui] => N0000145918
[conceptKind] => DRUG_KIND )
[1] => SimpleXMLElement Object (
[conceptName] => Aspirin
[conceptNui] => N0000006582
[conceptKind] => INGREDIENT_KIND )
)
)
)
