You also need to check for <script type="text/javascript">; 2. You have to strtolower() both strings in order to eliminate capitalization differences; 3. and the tougher: how do you check for this one: "<script language ='javascript' \t>", where "\t" is a tab character? And obviously all the possible combinations...
