HTML, XHTML, CSS and JAVA debugging and practice tests/examples

[Combat squirrel]

As title, is there a good place that gives online tests and examples, iv been to w3c school and theres some good knowledge tests there, but id like some worked examples for debugging some code etc, i want to practice.

There is no debugging of xHTML as such, and by "JAVA" do you actually mean Java, or Javascript?

Both Java and Javascript, I guess I mean 'debugging' of HTML in terms of making a HTML page work/display properly if there is an error in code.

First lesson to learn, in that case, is that Javascript and Java have nothing to do with each other.

Well yes I know that much but I still want to learn BOTH

Basically I did it years ago and want to relearn it, I know bits of everything, but want some worked examples to enable me to 'revise' how to go through code again and debug, write and change it again.

Thats cool thanks for that, but im more after a website that offers excercises and tasks for one to learn, for example like the w3c school exam, but with lines of code to look at it. I.e. here is this code:

<img src="xyz">image here etc etc

find the code error and hit 'ok' to see if you have passed this question......... etc but obviously more complex and challenging, I need to get the brain cells working again

<img> should alway have alt="Image description/image title" and should be closed.

<img src="xyz" alt="image of xyz" />

*sigh, yes yes indeed, thanks, HOWEVER that was JUST A ROUGH EXAMPLE of what sort of thing im after, I dont need specific help on anything, i just want some guides and tutorials

Yeah got those, just want something totally random and not stuff like a CD attachment to a learn stuff book, I want fresh previously unseen stuff - anyone have any XHTML, CSS, Javascript OR Java code they want looking at ?
