Sorry if this is too off topic for the forum, but I think a lot fo folks have the same basic questions.
I've got a pretty good handle on css/html, and I could get through xml is that's what's needed, just need a shove in the right direction.
If you come here and ask 'How do I use a jackhammer?', we might ask 'Why do you need to use a jackhammer'? If the answer is 'to knock my grandmother's head off to let out the evil spirits that gave her cancer', then maybe the problem is actually unrelated to jackhammers.
