Cruisecontrol.net中的条件参数

有没有办法混淆Cruisecontrol.net 1.6中的“与”和“或”运算符?我的if条件如下:

if ((A="a" && a="a") || (B="b" && b="b"))
{
    //Task to be done
}

用CC(OR部分)书写时也是一样的:

<conditional>
    <conditions>
        <orCondition>
            <conditions>
                <compareCondition value1="A" evaluation="equal" value2="a" />
                <compareCondition value1="B" evaluation="equal" value2="b" />
            </conditions>
        </orCondition>
    </conditions>
    <tasks>
        <!--Task to be done-->
    </tasks>
</conditional>

并且当用CC与and部分一起写入时:

<conditional>
    <conditions>
        <andCondition>
            <conditions>
                <compareCondition value1="a" evaluation="equal" value2="a" />
                <compareCondition value1="b" evaluation="equal" value2="b" />
            </conditions>
        </andCondition>
    </conditions>
    <tasks>
        <!--Task to be done-->
    </tasks>
</conditional>

我想把这两个都写成一个单独的条件运算。有可能吗?
