[jQuery] unrecognized expression after jquery update to 1.3.1

[jQuery] unrecognized expression after jquery update to 1.3.1


After I upgrade to Jquery.1.3.1 , I received this error in my code
uncaught exception: Syntax error, unrecognized expression:
[@id*=CountryIdentifier_]
http://ajax.googleapis.com/ajax/libs/jquery/1.3.1/jquery.min.js
Line 12
My expression is working fine with 1.2.6.
does any one why?
