Here is my flymake setup in .emacs file:
(when (load \"flymake\" t)
(defun flymake-pyflakes-init ()
(let* ((temp-file (flymake-init-create
OK I got it. here is what I did: first of all I found flymake.el file.(If you dont have it you probably have flymake.elc file under emacs installation.In that case just copy flymake.el file under your load path so it will be used instead of compiled version(.elc file) under insallation). than I found following function and commented .xml and .html bindings.

Other comment outed lines was already there. Now flymake does not work for html and xml files
