Online HTML Editor With Color Coding...How?

I recently wanted to make a program that is basically a HTML editor that detects whats in the tags. Like dreamweaver.

Is this possible?

If so can anyone help me find out how to do the color coding by detecting parts of a tag. Like <div id="something">Blablablab</div>

Can anyone plz help?

Have a look at using regular expressions rather than having to parse HTML.

I used regular expressions to retrieve all links from a page so I guess that you may be able to do the same with HTML links...

Here's a link for you;
