Flex: if-else logic

[RSAAdmin]

There is no "else" in Flex.

Obviously some else-type logic is easily approximated by testing both the condition and its opposite:

<if name="myVar" equal="1">

<!-- do stuff -->

</if>

<if name="myVar" notequal="1">

<!-- do other stuff -->

</if>

But what about evaluations that don't have an opposite in Flex, like bitwise "and":

<if name="myVar" and="1">

That just takes a couple extra steps:

1. default a temporary numeric variable to 0
2. perform the evaluation
3. if the evaluation succeeds (is "true") then set the temp var to 1
4. after the evaluation, if the temp var is still 0 - that is your "else"

For example:

<assign name="check" value="0"/>

<if name="myVar" and="1">

     <assign name="check" value="1"/>

     <!-- do stuff -->

</if>

<if name="check" equal="0">

     <!-- do other stuff -->

</if>
