PHP XML string parsing returns "Trying to get property of non-object"

Im trying to export some data from here (XML)

e.g and For example i'm trying to get the by using this code:

$xml = simplexml_load_string($response);
$results = $xml->Iteration[0]->{'Iteration_query-def'};

The thing is that returns the Notice written in post's title.

Am i loosing something in the path of XML file ?

Thank you.

try simplexml_load_file() to fetch data from url

$xml = simplexml_load_file('http://blast.ncbi.nlm.nih.gov/Blast.cgi?CMD=Get&RID=VY1DT6CN014&FORMAT_TYPE=XML');
echo $results = (string)$xml->BlastOutput_iterations->Iteration[0]->{'Iteration_query-def'};

Please notice structure of XML document. There is a parent for Iteration called 'BlastOutput_iterations'. Please try below script.

$results = $xml->BlastOutput_iterations->Iteration[0]->{'Iteration_query-def'};
