I have this simplexml result object:\[code\] object(SimpleXMLElement)#207 (2) { ["@attributes"]=> array(1) { ["version"]=> string(1) "1" } ["weather"]=> object(SimpleXMLElement)#206 (2) { ["@attributes"]=> array(1) { ["section"]=> string(1) "0" } ["problem_cause"]=> object(SimpleXMLElement)#94 (1) { ["@attributes"]=> array(1) { ["data"]=> string(0) "" } } } }\[/code\]I need to check if the node "problem_cause" exists. Even if it is empty, the result is an error.On the php manual, I found this php code that I modified for my needs:\[code\] function xml_child_exists($xml, $childpath) { $result = $xml->xpath($childpath); if (count($result)) { return true; } else { return false; } } if(xml_child_exists($xml, 'THE_PATH')) //error { return false; } return $xml;\[/code\]I have no idea what to put in place of the xpath query 'THE_PATH' to check if the node exists.Or is it better to convert the simplexml object to dom?
