From the post here, I know dropping the <?php and ?> can do the trick, however I think supporting
or something else is still necessary, because I do have different codes to store in KB, such as XML, ASP, PHP, HTML, all these require < and > characters, and in some case it is applicable to remove < and > , for example:<?xml version="1.0" encoding="UTF-8"?>
