What are the potential pitfalls of converting special characters in XML to their corresponding HTML entities in PHP?

Converting special characters in XML to their corresponding HTML entities in PHP can lead to potential issues such as double encoding, where the special characters are encoded twice, causing display problems. To solve this issue, you can use the htmlspecialchars_decode function in PHP to decode the HTML entities back to their original special characters before outputting the XML content. 

$xmlContent = '<xml><example><test></example></xml>';
$decodedContent = htmlspecialchars_decode($xmlContent);
echo $decodedContent;
