Question

This should be really easy, but I’m just not seeing how to do it. I just need to access the value of the element document-id.

print_r($http_result_simplexml);

gives…

SimpleXMLElement Object ( [document-id] => 1234 ) 

I need to get this document ID number, but I’m not getting how to do it. I tried $http_result_simplexml[‘document-id’], but it doesn’t work. What I’m understading is that ‘document-id’ is the element, and ‘1234’ is the value of the element. Another method I’ve come across is $http_result_simplexml->element_name, but obvisouly, the minus sign in ‘document-id’ won’t work there.. I’m sure this is something absurdly simple..

(please correct me if that’s not called the “element”)

Answer 1

Access the element you are looking for:
$document_id = $http_result_simplexml->{'document-id'}

$document_id will also be a SimpleXMLObject! so you have to cast the value, using either:
$document_id = (string)$document_id; or $document_id = (int)$document_id;
depending on whether you want a string or integer.

print_r($document_id); //should give the result you want now
