If Tag

The if tag implements a simple IF THEN conditional branch. It uses the following format:

<swe:if condition="business_service,business_service_method,argument1:value1,argument2:value2,..."> ... </swe:if>

where:

• condition. Defines the condition.
• argument:value defines an argument and value pair.

If SWE evaluates the condition to:

• TRUE. It processes the body of the if tag.
• FALSE. It ignores the body of the if tag.

You can use the if tag with any business service, such as a custom business service that examines an HTTP header. The output arguments for this business service must contain a property that includes the name of the business service method and a value of 1 or 0 that indicates if the condition is true or false.

The predefined Web Engine State Properties business service supports the following conditions:

• IsEvenRow
• IsOddRow
• IsCurrentRow
• IsErrorRow
• IsRowMultipleOf
• IsRowPositionOf
• IsLastDisplayedRow
• IsHighInteractive
• IsHighInteractiveApplet
• IsLowInteractive
• Invalid
