Create permalink or link to w3c validator

I want to print out the full URL of the page I am on so I can do some basic validation here:

<a href="http://validator.w3.org/check?uri=http://www.adrianramsay.org.uk/[*alias*].html">Validate XHTML</a>

Because some pages are in folders / containers, that doesn’t work .. I guess I might need some recursion; but does anyone have a ready made answer?

Why not put this in your template and let the validator workout the url?

bunk58 has the most correct answer but just so you know......would’ve been what you were looking for.

Thanks all!
