pc:if

As an element introduces script sections that execute only if a given condition applies, or does not apply.

Syntax

<pc:if test="xpath >> boolean">

<pc:then>

conditional-content

</pc:then>

<pc:else>

conditional-content

</pc:else>

</pc:if>

The value of the required test attribute evaluates to a boolean. If it evaluates to true() according to the rules of the xslutil:test() Blend function, the content of the required <pc:then> child element is processed. If it evaluates to false(), the content of the optional <pc:else> element is processed if it exists.

If you omit the <pc:else> element, you can write the construct in a more compressed format by using pc:if-then.

Examples

The element <PrintThis/> is written to standard output in:

<pc:if test="1=1">
<pc:then> <PrintThis/> </pc:then>
<pc:else> <PrintThat/> </pc:else>
</pc:if>

The element <PrintThat/> is written to standard output in:

<pc:if test="1=2">
<pc:then> <PrintThis/> </pc:then>
<pc:else> <PrintThat/> </pc:else>
</pc:if>

Syntax

<pc:directive pc:if="xpath >> boolean" ... />

The parent directive is only executed if the value of pc:if evaluates to Boolean true().

Example

In this example, the output text is printed only if the $doaction variable evaluates to true() according to the rules of the xslutil:test() Blend function:

<pc:text pc:if="xslutil:test($doaction)">The action will be done.</pc:text>
