How can the output of a template parser function be further processed before being displayed?

The output of a template parser function can be further processed before being displayed by using PHP functions such as htmlspecialchars() to sanitize the output and prevent cross-site scripting attacks. This can help ensure that the content displayed is safe and does not contain any harmful code. 

// Example of further processing the output of a template parser function
$templateOutput = "<script>alert('Hello, world!');</script>";
$processedOutput = htmlspecialchars($templateOutput);

echo $processedOutput;
