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.

Use

HTML Tidy

HTML Tidy is an open source program and library for checking and generating clean XHTML/HTML

CSE HTML Validator Lite - FREE HTML Editor and HTML Checker for Windows validator

and another by using firefox addon which can be downloaded from mozilla site

Emacs + flymake + tidy. http://www.emacswiki.org/emacs/FlyMake#toc18
