Allowing user video input

Hi regexp experts

I have been trying to think of an appropirate regexp that
would allow
users to post video code on a site but not allow them to add
any
malicious code.

<object>
<embed>
</embed>
</object>

or

<embed>
</embed>

or

<embed   />

the attributes of the tags must allow no <script or
script
also it must not allow java applets.

So you don't want '<script', 'script',
'<applet' ....tags show up in
your input strings? Is this correct? then you may want to
try something
like:

  ^(?!.*<?script)(?!.*<applet)

you can append more (?!.*TEXT) to forbid any other TEXTs you
dislike,
i.e. 

  ^(?!.*<?script)(?!.*<applet)(?!.*TEXT)
