What are the potential pitfalls of adding pseudo-line breaks in XML?

Adding pseudo-line breaks in XML can lead to parsing errors and invalid XML documents. It is important to properly encode special characters in XML to avoid these issues. To solve this problem, you can use PHP's htmlspecialchars function to encode special characters before adding pseudo-line breaks.

$xmlData = "<data>";
$xmlData .= "<name>" . htmlspecialchars($name) . "</name>";
$xmlData .= "<description>" . htmlspecialchars($description) . "</description>";
$xmlData .= "</data>";
