Purpose: Evaluates the Expression after the if tag. Its result must be of type Boolean. If the expression evaluates to true, the heitml code following the if tag is performed, otherwise the evaluation repeats for the expression of every elsif tag. If no elsif expression evaluates to true, and if the else tag has been specified, the heitml code following the else tag is performed.

Example:

heitml input:
<if x == y> <DoThisProcedure> <DoThisOneToo> <else> <ShowErrorMessage> </if>

Note: The if, elsif, and else Tag is Case Sensitive, which means heitml will not recognize it if you use capital letters (e.g. <IF Expression>, <ELSIF Expression> or <ELSE>).
