PHP cURL XML Response with single XML Tag

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:

<err>ERROR MESSAGE HERE</err>

I'm currently using this code to parse the API response:

$parsedresponse = simplexml_load_string($response);

The $parsedresponse variable contains only the error message. However, I need a way to check if the <err> tag is present so I know if there was an error. I can't seem to figure out how to do this...

Thank you!

If err tag is the root tag use the following condition to trace the error.

if ($parsedresponse->getName()=='err'){
    // got it
}

If its the first child use

if (isset($parsedresponse->err)){
    // got it
}
  • negate the condition as necessary.

<?php

$xml = <<<EOF
<?xml version="1.0" encoding="UTF-8"?>
<err>ERROR MESSAGE HERE</err>
EOF;

$sxml = simplexml_load_string($xml);

if ($sxml->getName() != "err") print('not set');
else print('set');

?>
