When working with XML responses using SimpleXMLElement in PHP, it is important to access specific node content accurately. To do this, you can use XPath expressions to target the desired nodes within the XML structure. By utilizing XPath, you can efficiently navigate through the XML document and extract the necessary data. 

$xml = new SimpleXMLElement($xmlString);
