Looking through the a Toyota Dealer parts catalog, there are two varieties of windshield for this car, heated and non-heated. According to the linked site, the heated model is compatible with a 1997 Avalon XL, as well as 1999 Camry LE's with the heated front glass option.
However, other sites offer conflicting information and indicate that the Avalon uses a different part # which isn't necessarily compatible with the Camry. If you want to be 100% sure that you're getting the right part, I'd look for either a heated or non-heated (depends on your car) windshield for a 1997-1999 Camry (these all seem to use the same part #, though some sites claim that a 1997-2001 windshield will fit a 99).
