Any free XHTML CSS editor with live(on type) W3C validation?

I know W3C Validator can do this but i need any free offline editor.

I would like to see live error in IDE if i'm not closing any tag mistakenly like this http://livevalidation.com/ not after coding whole document.

if anything is not pr开发者_高级运维oper in xhtml and css then ID should show error on that place in source code.
