Element "x" undefined when using validator

Tom Eldridge

Hi all I'm getting tons of these errors when running the w3c validator on my
template page.

Basically it will say for example: element "TITLE" undefined.

Do I need to put this into lowercase or uppercase or have I got completely
the wrong end of the stick and need to define my doctype to another?

Currently I have this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

In XHTML all element and attribute names must be lower case.

Which means there is no TITLE in the language your Doctype claims you are
using.

Although I suggest switching to HTML 4.01 Strict, it is far more suitable
for todays WWW.

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">

Case matters in XML, of which XHTML is an instance. All XHTML tag and
attribute names are lower-case.

It means you may have misdeclare the title element. It should be (it
must be) in your <head>...</head> section. If you declare your
<title>...</title> elsewhere than in the head section, then the
validator will report this as an error.

Elements and attributes in XHTML must be lowercased.
I suggest you use HTML 4.01 strict and not XHTML for your document.
Whatever you decide, it is in your best interest to use a strict DTD,
not a transitional DTD.

Recommended DTDs to use in your Web document.
http://www.w3.org/QA/2002/04/valid-dtd-list.html

Also, if you use Firefox, then you can check your documents offline with
HTML Tidy.

HTML Tidy validator for Firefox
http://users.skynet.be/mgueury/mozilla/

It will report you several errors that W3C markup validator will not.
