I went back and tried version a again, blam it is/does work now ?!?!? I am not sure what changed but version a was the original code that wouldn't work. All the examples i had read, showed version a as a working version. I spent significant time trying version a with parens, spacing changes, different regex values to no avail. hence the creation of all the other versions. thanks for your help. -- http://mail.python.org/mailman/listinfo/python-list
