colorize code

[brown monkey]

any idea of colorizing code? such example is the <pre class=csharp>blah blah</pre> blah blah is colorize under the syntax of c#. i think there should be a pre.csharp{...}. and i think it's regex. any example is greatly appreciated. thanks in advance.

You would use egular expressions. Syntax highlighting is best done on the server side using perl or PHP. If you do a google search you'll find loads of examples.

For php the preg_replace() fuunction will be useful.

thanks mate. i'll do that. but i hope i will know the javascript version cause i'm just on the free servers mate and they only allow html on it so i had to do this on javascript. hope i can get some info on the net. if i get some, i'll post. thanks a lot.
