I want to parse "true" from xml below with php


<?xml version="1.0"?> 
<sparql xmlns="http://ift.tt/1H8JDsT"xmlns:xsi="http://ift.tt/ra1lAU"xsi:schemaLocation="http://ift.tt/1JDpQzH">

  <head>
    <link href="example2.rq" />
 </head>

  <boolean>true</boolean>

</sparql>

exactly the result is:

true

i try to use:


$curl_response = curl_exec($curly);
curl_close($curly);
$result = new SimpleXMLElement($curl_response);
print_r($result);
echo $result->sparql->boolean;

but it can't work. Is there any way to get the "true" from that xml and parse it to new variable?
