PHP cURL XML Response with single XML Tag

[DigDan]

I am using SimpleXML to load a response from an API call. However, if the server returns an error, it only returns a single XML tag with the error message: \[code\]<err>ERROR MESSAGE HERE</err>\[/code\]I'm currently using this code to parse the API response:\[code\]$parsedresponse = simplexml_load_string($response);\[/code\]The $parsedresponse variable contains only the error message. However, I need a way to check if the \[code\]<err>\[/code\] tag is present so I know if there was an error. I can't seem to figure out how to do this...Thank you!
