Consider following php code: $xml=<<<HSPXML <Hsp> <Hsp_query-from>10</Hsp_query-from> </Hsp> HSPXML; $Hsp = new SimpleXMLElement($xml); //You can't simply access Hsp_query-form element because '-' is PHP's operator var_dump($Hsp->Hsp_query-from); var_dump($Hsp["Hsp_query-from"]); var_dump(array_key_exists("Hsp_query-from" , $Hsp)); //Prints: /* int(0) NULL bool(true) */ //so the key exists! but is inaccessible with[] (and {}) //Way around is to create an additional array: $hsp_array = array(); foreach($Hsp as $key=>$value) { $hsp_array[$key]=$value; } var_dump($hsp_array["Hsp_query-from"]); //the proper result: object(SimpleXMLElement)#3 (1) { [0]=> string(2) "10" } produced PHP 5.2.5, Windows, Wamp 2.0 ---- Server IP: 82.160.94.10 Probable Submitter: 85.128.94.162 ---- Manual Page -- http://www.php.net/manual/en/ref.simplexml.php Edit -- https://master.php.net/note/edit/81585 Del: integrated -- https://master.php.net/note/delete/81585/integrated Del: useless -- https://master.php.net/note/delete/81585/useless Del: bad code -- https://master.php.net/note/delete/81585/bad+code Del: spam -- https://master.php.net/note/delete/81585/spam Del: non-english -- https://master.php.net/note/delete/81585/non-english Del: in docs -- https://master.php.net/note/delete/81585/in+docs Del: other reasons-- https://master.php.net/note/delete/81585 Reject -- https://master.php.net/note/reject/81585 Search -- https://master.php.net/manage/user-notes.php
