Just came across this very good XHTML Tutorial. It starts from first principles and covers all the basics in a very easy manner. I like the fact that it starts you off by using Notepad as an editor. I think this is an excellent way to learn and understand how XHTML works. By all means move to Dreamweaver later but understanding the code is extremely important. Also check out this useful list of other XHTML tutorials for more help and this excellent XHTML resource site.
