Is there anyway to implement XOR in javascript

Question

I\'m trying to implement XOR in javascript in the following way:

   // XOR validation
   if ((isEmptyString(firstStr) && !isEmptyString(secondStr)) |

@george, I like your function for its capability to take in more than 2 operands. I have a slight improvement to make it return faster:

function xor() {
    for (var i=arguments.length-1, trueCount=0; i>=0; --i)
        if (arguments[i]) {
            if (trueCount)
                return false
            ++trueCount;
        }
    return trueCount & 1;
}
