   <true>
     ...
   </true>
   <false>
     ...
   </false> 
</if>

Attributes

Attribute Description Value
condition Required. An ObjectScript expression that, if true, causes the contents of the <true> element to execute. If false, the contents of the <false> element are executed. An expression that evaluates to the integer value 1 (if true) or 0 (if false).

Elements

Element Purpose
<annotation> Optional. A text string that describes the <if> element.
<true> Optional. If the condition is true, activities inside the <true> element are executed.
<false> Optional. If the condition is false, activities inside the <false> element are executed.

Description

The <if> element evaluates an expression and, depending on its value, executes one of two sets of activities (one if the expression evaluates to a true value, the other if it evaluates to a false value).

The <if> element may contain a <true> element and a <false> element which define the actions to execute if the expression evaluates to true or false, respectively.

If both <true> and <false> elements are provided, they may appear within the <if> element in any order.

If the condition is true and there is no <true> element, or if the condition is false and there is no <false> element, no activity results from the <if> element.
